Question

2. Resolva as equações a seguir
c) 4x = 200
a) X - 10 - 25
d) 7x = 5x +3
b) 4x - 15 = 2x + 7
​

Answer 1

Resposta:

c)4×50=200 ,a)35-10=25,

Answer 2

c) 4x = 200

x = 200/4

x= 50

a) X - 10 - 25

X = 25 + 10

X = 35

d) 7x = 5x + 3

7x - 5x = 3

2x = 3

x= 3/2

x= 1,5

b) 4x - 15 = 2x + 7

4x - 2x = 7 + 15

2x = 22

x= 22/2

x = 11

Bons estudos.
