Question

encontre o valor do x;
a) 2x+18=200
b)x+15=250
c)2x+100=240
d)4x+200=400

Answer 1

Resposta:

A) 2x + 18 = 200

2x = 200 - 18

2x = 182

x = 182 / 2

x = 91

B) x + 15 = 250

x = 250 - 15

x = 235

C) 2x + 100 = 240

2x = 240 - 100

2x = 140

x = 140 / 2

x = 70

D) 4x + 200 = 400

4x = 400 - 200

4x = 200

x = 200 / 4

x = 50
