X - 3y = 7 3x + 3y = 9 Please use system of elimination to answer please

yawa3891 [41]

ANSWER:

x=4 and y= -1

Explanation:

Add these equations to eliminate y:
4x=6

Then solve 4x =16 for x:
4x=16

4x/4 = 16/4 (divide both sides by 4)

x=4

Now that we have found x lets plug it back in to solve for y.
Write down an original equation:

x-3y=7

Substitute 4 for x-3y=7:

4-3y=7

-3y+4=7 (simplify both sides of the equation)

-3y+4+ (-4) = 7+ (-4) (add -4 to both sides of the equation)

-3y = 3

-3y/-3 = 3/-3 (Divide both sides by -3)

y= -1

I HOPE THIS HELPS
