Question

Find the solutions of the systems -6x-2y=8 and 7x-2y=-5

Answer 1

y=4

x= 3/7

Explanation:

2y=8

Divide both sides by 2

2y÷2=8÷2

A.) y=4

Substitute 4 for y

7x−2y=−5

7x+(−2)(4)=−5

Simplify both sides of the equation.

7x−8=−5

Add 8 to both sides

7x−8+8=−5+8

7x=3

Divide both sides by 7

7x÷7= 3÷7

x= 3
