What is the solution to the system of equation -2x+6y=-38 3x-4y=32

Alla [95]

Answer:

x= 4

y= -5

Step-by-step explanation:

-2x+6y=-38 equation 1

3x-4y=32 equation 2

using equation 1 we have:

-2x+6y=-38

6y +38 = 2x

3y + 19 = x equation 3

using equation 3 in equation 2 we have:

3(3y + 19) - 4y = 32

9y + 57 -4y =32

5y = 32 -57

5y = -25

y= -25/5

y = -5

so we have:

3y + 19 = x

3(-5) +19 = x

x= 4
