Question

Solve the equation. If the equation is an identity, choose identity. If it has no solution, choose no solution.

−12x+1=7x−14

A. 2
B. −2
C. identity
D. no solution

Answer 1

There is one solution x = 15/19

Explanation:

−12x+1=7x−14

Add 12x to each side

−12x+12x+1=7x+12x−14

1 = 19x-14

Add 14 to each side

1+14 = 19x-14+14

15 = 19x

Divide by 19

15/19 = 19x/19

15/19 =x

There is one solution x = 15/19
