1. Solving One-Step Equations
COURSE 3 LESSON 2-1
Solve = 14. y –3
= 14 y –3
Since y is divided by –3, you must multiply each side by –3 to isolate y.
–3 • = –3 • 14 Multiply each side by –3. y –3
y = –42 Simplify.
14 Substitute –42 for y.
–42 –3
14 = Divide.
Check the solution in the
original equation.
Check = 14 y

2. Solving One-Step Equations
COURSE 3 LESSON 2-1
Solve 265 = –5x.
265 = –5x
Since x is multiplied by –5, you must divide each side by –5 to isolate x.
Divide each side by –5.
265 –5
–5x =
Simplify.
–53 = x
Check 265 = –5x
Check the solution in the
original equation.
–5(–53) Substitute –53 for x.
265 = Multiply.
