Question

(A)X+2=12
(B)x-27=129
(C)27+129=x
(D)x+27+×=129

Answer 1

A) x + 2 = 12 ----- x = 12 - 2 ---- x = 10

(B) x - 27 = 129 ------ x = 129 + 27 ------ x = 156

(C) 27 + 129 = x ------ x = 156

(D) x + 27 + x = 129 ----- 2x = 129 - 27 ------ 2x = 102 ---- x = 102/2 --- x = 51

Answer 2

A)
x + 2 = 12
x = 12 - 2
x = 10

B)
x - 27 = 129
x = 129 + 27
x = 156

C)
27 + 129 = x
x = 156

D)
x + 27 + x = 129
2x + 27 = 129
2x = 129 - 27
2x = 102
x = 102 / 2
x = 51
