Question

me ajudem pfvr
c)x-4=3



d)3x=15


e)x/3=7


f)3x-4=2x+8


g)7x-2+4=10+5x​

Answer 1

Resposta:

c)x - 4 = 3

x = 3 + 4

x = 7

d)3x = 15

x = $\frac{15}{3}$

x = 5

e)$\frac{x}{3}$ = 7

x = 7 · 3

x = 21

f)3x - 4 = 2x + 8

3x - 2x = 8 + 4

x = 12

g)7x - 2 + 4 = 10 + 5x​

7x - 5x =  10 + 2 - 4

2x = 8

x = $\frac{8}{2}$

x = 4

Answer 2

Resposta:

c) x-4=3

x=4+3

x=7

D)3x=15

x=15÷3

x=5

E)x/3=7

x=3.7

x=21

F)3x-4=2x+8

3x-2x=8+4

x=12

G)7x-2+4=10+5x

7x-5x=10-4+2

2x=8

x=8÷2

x=4
