Question 695884: Solve the system of equations and enter your answer as an ordered pair .
6x-4y=-8
11x+4y=76 Found 2 solutions by ReadingBoosters, BigToosie:Answer by ReadingBoosters(3246) (Show Source):
You can put this solution on YOUR website! Since the y coefficients are the same with opposite signs, add the equations to elimate y and solve for x.
...
6x + 11x -4y + 4y = -8 + 76
17x = 68
x = 4
...
If x is 4, solve for y using either of the equations
6(4) - 4y = - 8
24 - 4y = -8
-4y = -8 - 24
-4y = - 32
y = 8
...
solution is (4, 8)

You can put this solution on YOUR website! To Solve the system of equations first start by solving for one of the variables either using elimination method or substitution method here we will use the elimination method.
6x - 4y = -8
11x + 4y = 76
Here 4y will cancel out and you are left with
17x = 68
Divide 17 on both sides
17x/17 = 68/17
x = 4
Now plug in x in either equation to solve for y
6(4) - 4y = -8
24 -4y = -8
subtract 24 on both sides
-4y = -32
Divide by -4 on both sides
y = 8
Therefore your order pair for this system of equation is (4,8)
