Question

a) x - 2(x - 2) = 3x
b) 11 - x = 3x – 5(2x – 1)
c) x- 4(x + 2) = x + 5 – 3x
d) 4(x - 2) + 3 = 1 -3(2-×)​

Answer 1

a) x-2(x-2)=3x

x-2x+4=3x

4= 3x+x

4=4x

x = 1

b) 11 - x = 3x - 5(2x - 1)

11 - x = 3x - 10x + 5

11-5 = 8x

6 = 8x

x = 6/8 = 3/4

c) x - 4(x+2) = x + 5 - 3x

x -4x - 8 = x + 5 - 3x

x = -13

d) 4(x - 2) + 3 = 1 -3(2-x)

4x - 8 + 3 = 1 -6 +3x

x = 0
