Question

1. What value of x makes the equation 12x - 15 = 6 - 3x true?

Answer 1

x=1.4

Explanation:

add 3x to both sides to get 15x-15=6

Then add 15 to both sides to get 15x=21

Then divide by 15 on both sides to get x=1.4

Answer 2

x = 7/5

Explanation:

Step 1: Write out equation

12x - 15 = 6 - 3x

Step 2: Add 3x to both sides

15x - 15 = 6

Step 3: Add 15 to both sides

15x = 21

Step 4: Divide both sides by 15

x = 7/5
