B) 5x+7=32+17 C) 6x-5=5x+25 Me ajudem pfv

Answer 1

a)4x-2x=15+15
2x=30
x =30/2
x=15

b)5x=32+17-7
5x=42
x=42/5'
x=8,4

c)6x-5x=25+5
x=30

Answer 2

A) 4x-15 = 2x+15
4x-2x = +15+15
2x = +30
x = 30÷2
x = 15

B) 5x + 7 = 32 + 17
5x = 32 + 17 - 7
5 x = 42
x = 42÷5
x = 8,4

C)6x - 5 = 5x + 25
6x - 5x = + 25 + 5
x = 30
