Since both are equations are set equal to y, then:
12x^2 - 5 = 7 - 7x
Bring everything to the left side:
12x^2 - 5 - 7 + 7x = 0
Simplify:
12x^2 + 7x - 12 = 0
Factor:
(4x - 3)(3x + 4) = 0
Set each factor equal to 0 and solve for x
4x - 3 = 0
4x = 3
x = 3/4
and
3x + 4 = 0
3x = -4
x = -4/3
Solution: x = -4/3 or 3/4
