Question

Solve for x.
۔
8x - 3/ 4x +3
8x - 3 + 4 + 3 = 180
12x + [?] = 180

Answer 1

let 8x-3+4+3=180 be equation 1

and let12x+[?]=180 be equation 2

solving for x in equation one we have

x=22

putting x=22 into equation 2

we have 12×22+[?]=180

264+[?]=180

[?]=180-264

=-84

i.e 12x+[-84]=180
