Question

A) 2x-10=x+1 B) 4x-3=-2x+21 C) 5x-10=90 d) 4x-8=32 mim ajudem é valendo nota

Answer 1

A)2x-10=x+1
2x-x+1+10
x=11

B)4x-3=-2x+21
4x+2x=+21+3
6x=24
x=24÷6
x=4

c)5x-10=90
5x=90+10
5x=100
x=100÷5
x=20

d)4x-8=32
4x=32+8
4x=40
x=40÷4
x=10

Bons estudos!

Answer 2

Vamos lá. ..

a)

2x - 10 = x + 1
2x- x = 1 + 10

x = 11


b)

4x - 3 = - 2x + 21
4x + 2x = 21 + 3
6x = 24
x = 24/6

x = 4


c)

5x - 10 = 90
5x = 90 + 10
5x = 100
x = 100/5

x = 20


d)

4x - 8 = 32
4x = 32 + 8
4x = 40
x = 40/4

x = 10


Espero ter ajudado !!!
