Algebra
Linear equations in one variable
Isolate x, distribute, and watch the sign when you move terms.
HomeSAT MathSAT algebra practice
SAT algebra practice — the largest Math domain.
Algebra is about 35% of Digital SAT Math. If linear equations are leaking points, more geometry will not hide it. See the six skills, try one sample, then practice the rest in Prepful.
Topics
Six algebra skills, in the order they build.
Algebra
Linear equations in two variables
Slope-intercept and standard form. Match a graph to an equation.
Algebra
Systems of linear equations
Substitution and elimination. One solution, none, or infinitely many.
Algebra
Linear inequalities
Flip the inequality when you multiply by a negative. Shade the right half.
Algebra
Linear functions
Rate of change, intercepts, and what a parameter does to the line.
Algebra
Linear equations as word problems
Translate a story into 3x + 5 = 20 before you reach for the calculator.
One original sample — linear equations in one variable.
Solve for x: 3(x − 2) = 2x + 5
- A 1
- B 7
- C 11
- D 13
Show working
Distribute: 3x − 6 = 2x + 5. Subtract 2x from both sides: x − 6 = 5. Add 6: x = 11. The calculator is allowed on Digital SAT Math; it does not replace this setup.
Full Study Guides and extra items stay in the logged-in app. This page is the public intro: six skills, one original sample, and a path into practice.
Common misses we see on algebra.
- Sign errors after distributing a negative — especially in inequalities, where the symbol must flip.
- Solving for the wrong variable in a word problem — the story asked for total cost, not x.
- Treating a system as one equation — two lines need two constraints.
After a diagnostic, put algebra weeks on the study plan if Math is the gap. The section hub is SAT math practice. Geometry formulas live on the SAT math formula sheet explainer — they do not replace linear setup. If you still need a total, use the score calculator.
Algebra questions
Why this page exists.
How much of Digital SAT Math is Algebra?
About 35% of the Math section, using Prepful's exam_dimension weight for sat.math.algebra. It is the largest Math domain, which is why this page is the first public skill landing.
Can I read the full Study Guide here?
Not yet. Full guides stay behind login. This page is an intro, the six skills, one original sample, and a path into onboarding.
Is the sample an official College Board item?
No. It is an original linear-equation item written for this page. Official items live in College Board materials.
Practice the rest on Prepful.
Take the 16-question diagnostic, then follow algebra missions instead of random mixed sets.
