Question

determine as medidas de x e y.​

Answer 1

Explicação passo-a-passo:

9y + 16 = 7y + 40

9y - 7y = 40 - 16

2y = 24

y = 12

9.12 + 16 + 7.12 +40 + 2x = 360

108 + 16 + 84 + 40 + 2x = 360

2x = 360 - 248

2x = 112

x = 56

5x + 3 = y

12x + 2 + y = 90

12x + 2 + 5x + 3 = 90

17x = 90 - 2 - 3

17x = 85

x = 85/17

x = 5

5x + 3 = y

5.5 +3 = y

y = 28
