Question

Use the elimination method to solve the system of equations. Choose the correct ordered

6x + 4y = 32
–6x + 4y = 8

Answer 1

ok so set your two equations on top of each other

6x + 4y = 32
-6x + 4y = 8
-------------------------------



notice that 6x and the -6x will be 0 so they get eliminated

so what do we have left after getting ride of those


4y = 32
4y = 8
-----------------------

so now lets keep adding down

8y = 40

now solve for y but dividing so y = 5

now that you know what your (y) value is y = 5 take 5 and plug it back into one of the original equations to get your x value. I chose the following


6x + 4y = 32
6x + 4(5) = 32
6x + 20 = 32
6x = 12
x = 2


so your point is ( 2 , 5 )

hope this helps
