Solve, simplify, and manipulate single-variable linear equations on the SAT.
Linear equations in one variable show up repeatedly on the Digital SAT Math section and are the foundation of the Algebra domain. Mastering this skill means being able to isolate variables, distribute, combine like terms, and solve equations that include fractions or decimals in under 40 seconds.
These are real practice questions pulled from our Digital SAT bank. Try each one before reading the highlighted correct answer.
