Challenging Equations with Variable on One Side

3a + 9 + 4a = 2

• -1

• 1

• no solution

• -7

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

After moving the constant to one side in the following equation, what would be the result: 70x + 48 = -22

• 70x = 70

• 70x = -70

• 70x + 70 = 0

Solve the equation:
-5x = 25

• x = 20

• x = -20

• x = -5

• x = 5

2x + 3(5x - 7) = 47

• x = 1

• x = 2

• x = 3

• x = 4

-91 = -6a + 5(1 +6a)

• -12

• 0

• 4

• -4

Solve for the variable k in the following equation: 7k − 1 − 6k = −6

• k = -2

• k = -3

• k = -4

• k = -5

Solve.

(2x - 3) / 4 = 9

• x = 24

• x = 12

• x = 17.5

• x = 19.5

Which equation has a solution of x = 1

• 2x + 1 = 12

• 5x - 2 = 3
