Question

a)4(x+3)=20
b)5(2x-1)=2(x+4)
c)10-2(x+3)=8+3(2x+5)
d)x-2(x-1)=4-3(x-2)
e)2x-3(4-x)=5+4(2x+1)
f)6x-7(1-x)-(10x+4)=0

Answer 1

a)4x+12 = 20
4x = 20-12
4x=8
x=2

b)10x-5=2x+8
10x-2x=8+5
8x=13
x=13/8

c)10-2x-3=8+6x+15
-2x-6x=8+15-10+3
-8x=16.(-1)
8x=-16
x=2

d)x-2x+2=4-3x+6
x-2x+3x=4+6-2
2x=8
x=4

e)2x-16+3x=5+8x+4
2x+3x-8x=5+4+16
-3x=25.(-1)
3x=25
x=25/3

f)6x-7+7x-10x+4=0
6x+7x-10x=7-4
2x=3
x=3/2

Answer 2

a) 4x + 12 = 20 4x = 20-12= 4x = 8 x= 8/4 = 2
b) 10x-5=2x+8 10x-2x=8+5= 8x =13 x =13/8 =
c)10-2x+6=8+6x+5 2x-6x=8+5-10 3x= 3=x= 3/3=1
