Solve Multi-Step Equations with Variable on One Side

What is the first step in solving the equation 2a - 4(a - 5) = 10

• Add 4 to both sides

• Add the 2a and a 

• Distribute 4 to a and -5

• Distribute -4 to a and -5

4x + 10 = -26

• 4

• -4

• -9

• 9

The objective when solving an equation is to....

• isolate the variable.

• check the solution.

• guess and check.

• Combine Like Terms.

3a + 9 + 4a = 2

• -1

• 1

• no solution

• -7

• a= -2

• a= -7.5

• a= 2

• a= 6

• a= 9

• a= -9

• a= -5

• a= 5

• x = 2

• x = -2

• x = -10

• x = 4

Solve for x.

• 55

• 60

• 15

• 35

The goal of solving a one, two, or multi-step equations is to:

• Find the coefficient

• Find the value of the variable

• Find the constant

• Be confused

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4
