Question

Find the solution of the system of equations.

Answer 1

Answer:

x = 8

y = 10

Step-by-step explanation:

Multiply the first equation by -1

-1 * (-8x + 4y) = -24

8x - 4y = 24 now add this to second equation

8x - 4y - 7x + 4y = 24 - 16 add like terms (keep in mind, -4y will eliminate +4y)

x = 8 to find the value of y we can use this information

-8x + 4y = -24 replace x with 8

-8*8 + 4y = -24

-64 + 4y = -24 add 64 to both sides

4y = 40 divide both sides by 4

y = 10
