Solve using substitution<br> 3x+5y=-4<br> x+5y=2

Paha777 [63]

Answer:

x = -3

y = 1

Step-by-step explanation:

3x + 5y = -4

x + 5y = 2 (Solve for x) ------ New Equation: x = 2 - 5y

Solve for the first equation by plugging in the value of x, which is 2 - 5y.

3(2 - 5y) + 5y = -4

6 - 15y + 5y = -4

-10y = -10

y = 1

Use the value of y to solve for x

x + 5(1) = 2

x = 2-5

x = -3
