Answer 1

a)x-8=17

x=17-8

x=25

b)2x-5=7

2x=5+7

2x=12

x=12/2

x=6

c)x-10=10

x=10+10

x=20

d)3x-15=12

3x=12+15

3x=27

x=27/3

Answer 2

Olá! Bom dia.

a)
X - 8 = 17
X = 17 + 8
X = 25

b)
2x - 5 = 7
2x = 7 + 5
2x = 12
X = 12 ÷ 2
X = 6

C)
X - 10 = 10
X = 10 + 10
X = 20

d)
3x - 15 = 12
3x = 12 + 15
3x = 27
X = 27 ÷ 3
X = 9
