Question

(a)2(x-6)=-3(x+5) / (b) x/2+x/4=1/2 / (c) x/2-x/4=5

Answer 1

a)  2(x-6) = -3(x+5)
     2x-12 = -3x - 15
     2x+3x = +12 - 15
     5x = -3
     x = -3/5

b) x/2 + x/4 = 1/2
    2x/4 + x/4 = 1/2
    3x/4 = 1/2
    3x = 4/2
    3x = 2
    x = 2/3

c) x/2 - x/4 = 5
    2x/4 - x/4 = 5
    x/4 = 5
    x = 2-
