find the value of x in the expression if a= 3x + 51 and b equals 6x - 15

Question

X equals what

Answer 1

To find the value of x, we need to set the expressions for a and b equal to each other:

3x + 51 = 6x - 15

Now, we can solve this equation for x.

Subtract 3x from both sides:
51 = 3x - 15

Add 15 to both sides:
66 = 3x

Divide both sides by 3:
x = 22

Therefore, x equals 22.
