Question

Solve 5+x=3(x-7)+6

A. 31/2

B. There are infinitely many solutions.

O C. x= 3

D. x= 10

Answer 1

Answer:x= 10

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Answer 2

D

Explanation:

5 + x = 3(x - 7) + 6

~Distribute right sides

5 + x = 3x - 21 + 6

~Combine like terms

5 + x = 3x - 15

~Subtract 5 to both sides

x = 3x - 20

~Subtract 3x to both sides

-2x = -20

~Divide -2 to both sides

x = 10

Best of Luck!
