Question

x + 1 + x + 3 + x +1 + x + 3 = 36

2(x + 1 ) + 2(x + 3) = 36
 
resolver as duas

Answer 1

x + 1 + x + 3 + x + 1 + x + 3 = 36

4x + 8 = 36

4x = 36 - 8

4x = 28

x = 28/4

x = 7

2(x + 1) + 2(x + 3) = 36

2.x + 2.1 + 2.x + 2.3 = 36

2x + 2 + 2x + 6 = 36

4x + 8 = 36

4x = 36 - 8

4x = 28

x = 28/4

x = 7

Answer 2

x + x + x + x = 36 - 1 - 3 - 1 - 3
4x = 28
x = 28 ÷ 4
x = 7

2x + 2 + 2x + 6 = 36
2x + 2x = 36 - 2 - 6
4x = 28
x = 28 ÷ 4
x = 7
