a) x + 2 = 7

5+2= 7

b) 5x = 50

c) - 7x = 14

d) 3x - 24 = 0

e) = 30

f) 2x = 1

g) = 1

h) = 2

i) 2 - 3x = - 9 - 4x

Answer 1

A) x+2=7

X=7-2

X=5

B)5x=50

X=50-5

X=45

C)-7x=14

X=14+7

X=21

D)3x-24=0

X=0+24-3

X=21

E)=30

F)2x=1

X=1-2

X=1

G)=1

H)=2

I)2-3x=-9-4x

1x=-5x

X=1-5x

X=-4x
