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

Mathematics
1 answer:
Daniel [21]3 years ago
7 0

Answer:

y=4  

x= 3/7

Step-by-step 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= <u>3</u>
