Answer 1

A)2x-1x=4-3 X=1 B)5x-4x=10-7 x=3 C)4x-2x=20+10 2x=30 x=30/2 x=15 D)8x-4x=-7+2 4x=-5 x=-5/4 x=-1,25 E)4x-2x=1+7 2x=8 x=8/2 x=4 F)9x+3x=27+9 12x=36 x=36/12 x=3

Answer 2

a) 2x+3=x+4
2x-x=4-3
x=1

b)5x+7=4x+10
5x-4x=10-7
x=3

c)4x-10=2x=20
4x-2x=20+10
2x=30
x=30/2
x=15


d)8x-2=4x-7
8x-4x=2-7
2x=5
x= -5/2
x= -2.5

e)4x-7=2x=1
4x-2x=1+7
2x=8
x=8/2
x=4

f) 9x-9+3x=27
9x+3x=27+9
12x=36
x=3
