Respuesta :
3x + 2y = 39
5x - y = 13
Multiplying the last by two:
10x - 2y = 26
Adding to the first
13x = 65
x = 5
y = 5x-13 =25-13=12
Check:
3(5)+2(12)=39 good
5(5)-12=13 good
Answer: x=5, y=12
Answer:
(5,12)
Step-by-step explanation:
Substitute the value of y
3x+2y=39
y=-13 +5x
Solve the equation
3x + 2(-13+5x)=39
Substitute the value of x
x=5
Solve the equation
y=-13+5x5
y=12
x=5 y=12
