Question

x+y=150
x-16=y+14

por favor quero a conta

Answer 1

x+y=150
x-y=14+16⇒x-y=30

corta y positivo com negativo
2x=180
x=180/2
x=90

x-y=30
90-y=30
y=90-30
y=60

Answer 2

{ x + y = 150
{ x - 16 = y + 14

>>>>>>>>>>>>>>>

{ x + y = 150
{ x - y = 14 + 16

>>>>>>>>>>>>>>

{ x + y = 150
{ x - y = 30
......................
.2x = 180
x = 180/2
x = 90

Sibstituindo em x = 90

x + y = 150
90 + y = 150
y = 150 - 90
y = 60
