Question

What does x equal if 5x+6=2x+15

Answer 1

5x+6=2×+15

-6. -6

5×=2×+9

-2. -2

3×=9

3×/3=9/3

×=3

Answer 2

To find the value of x, isolate the x first,

5x + 6 = 2x +15

Subtract 6 to both sides because whatever you do on one side you would always to on the other side.

5x = 2x + 9

Subtract 2x from both sides

3x = 9

Divide to isolate the x

x = 3 is your answer
