Question

Calcule o valor de x e y na figura.

Answer 1

A) x + 40 + 3x + x - 10 → 90
x + 3x + x → 90 - 40 + 10
5x → 60
x → 12

B) 2y + y - 15 → 90
3y → 90 + 15
3y → 105
y → 35

C) 2x + 4x → 90
6x → 90
x → 15

Answer 2

x+40+3x+x-10=90
3x+x+x=90+10-40
5x=60
x=60:5
x=12

y-15+2y=90
2y+y=90+15
3y=105
y=35
