Answer 1

a)3x-2x=1+2
X=3
b) 5x-8x=10-4
-3x=6
X=-2
c) wrong question
d) x-3x=1.5+2.5
-2x= 4
X=-2
f) 2.5x-2x=-3.5-.5
.5x=-4
X=-8

Answer 2

Answer:

a) 3x-2x=1+2

x=3

b)5x-8x=10-4

-3x=6

x=6÷3

x=2

c)-2x+3x+11+6

x+11+6

d)2x-x=4-13

x=-9

e)3x-x=1.5-2.5

2x=-1

x=-0.5

f)2.5x-2x=-3.5-0.5

.5x=-4

x=-8
