x-35=155
y+22=42
y+42=22
2x-3=25
-3x+2=-7
3x/5=-4/9.

Answer 1

Resposta:

x = 190

y = 20

y = -20

2x = 28 (automaticamente X = 14)

-3 = -9 ( -x = -3 então x = 3)

X=0,74 (3X = 2,222....

Explicação passo-a-passo:

X-35 = 155

X = 155 + 35

X = 190

__________

Y + 22 = 42

Y = 42 - 22

Y = 20

__________

Y + 42 = 22

Y = 22 - 42

Y = -20

___________

2x -3 = 25

2x = 25 + 3

2x = 28

28/2 = 14

X =14

____________

-3x + 2 = -7

-3x = -7 -2

-3x = -9

9/3 = -3

X = 3

____________

3x/5 = -4/9

3x = 0,444... ×5

3x = 2,222...

2,222/3

X = 0,74
