Question

(A) 5x-10=3x+12

(B) 6x+5=4+25

Answer 1

(A) 5x-10=3x+12
5x - 3x = 12 + 10
2x = 22
x = 22/2
x = 11

(B) 6x+5=4+25
6x = 4 + 25 - 5
6x = 29 - 5
6x = 24
x = 24/6
x = 4

Answer 2

Olá.

Letra "A"

5x - 10 = 3x + 12

5x - 3x = 12 + 10

2x = 12 + 10

2x = 22

x = 22/2

x = 11

Letra "B"

6x + 5 = 4 + 25

6x + 5 = 29

6x = 29-5

6x = 24

x = 24/6

x = 4
