Question

a) 2x+6+16=26

b) 8(x+3)=45

c) 5x=400

d)2x-3=33-x

e)x+30=150

Answer 1

Explicação passo-a-passo:

a) 2x+6+16=26

2x=26-6-16

2x=4

x=4/2

x=2

b) 8(x+3)=45

8x+24=45

8x=45-24

8x=21

x=21/8

c) 5x=400

x=400/5

x=80

d)2x-3=33-x

2x+x=33+3

3x=36

x=36/3

x=12

e)x+30=150

x=150-30

x=120

bons estudos..
