Question

x+82=40 | 4x=36 | 3x-=2x+8 | 7x-2+4=10 quais os resultados pfv

Answer 1

x + 82 = 40
x = 40 - 82
x = - 42

4x = 36
x = 36/4
x = 9

3x = 2x + 8
3x - 2x = 8
x = 8

7x - 2 + 4 = 10
7x = 10 + 2 - 4
7x = 8
x = 8/7

Answer 2

X + 82 = 40 X = 82 - 40 X = 42  4X = 36 X = 36 : 4 X = 9  3X = 2X + 8 3X - 2X = 8 X = 8  7X - 2 + 4 = 10 7X = 10 - 2 7X = 8 X = 8:7
