me ajudaaa pora fvv​

Answer 1

Resposta:

1.a) x=91

b) x=14

c) x=5

d) x=6

Explicação passo-a-passo:

5x-7=3x+5×35

5x-3x=5×35+7

2x=175+7

2x=182

x=182/2=91

3x-4=2x+10

3x-2x=10+4

x=14

2x-3=7(x-4)

2x-3=7x-28

2x-7x=-28+3

-5x=-25

5x=25

x=25/5=5

7(x+10)=8(x+8)

7x+70=8x+64

7x-8x=64-70

-x=-6

x=6
