Question

a) 3(x+5) - 6(x-2)=4(x+2)-5(x-4)
b)2(2x+7)+3(x-1)=6(x+3)-18
c)15(x-1)+4(2-3x)=9-2(x+4)
d)2x+5+3(3x-1)=8(1-7x)+2+3x
e)10•(3-x)+6(x+2)=13+7•(2x-1)

Answer 1

A) 3X + 5 - 6X + 12 = 4X + 8 - 5X + 20
3X - 6X - 4X + 5X = 20 + 8 - 5 - 12
- 2X = 11
X = - 11/2
b) 4x + 14 + 3x - 3 = 6x + 18 - 18
x = - 11
c) 15x - 15 + 8 - 12x = 9 - 2x - 8
5x = 8
x = 8/5
d) 2x + 5 + 9x - 3 = 8 - 56x + 2 + 3x
11x + 56x - 3x = 10 + 3 - 5
64x = 8
x = 8/64
x = 1/8
e) 30 - 10x + 6x + 12 = 13 + 14x - 7
- 18x = - 36
x = 36/18
x = 2
