Question

Topic is Solving Systems by Elimination. Need the work
6х + бу =- 12)
8x - 7y =- 16)

Answer 1

x= -2

y=0

Explanation:

first you need to turn the equations into ones that would make it easy to eliminate a variable

-4(6x+6y=-12)

3(8x-7y=-16)

then you need to make the new equations

-24x-24y=48

24x-21y=-48

then combine them with addition

-45y=0

then solve for the left over variable

y=0

then plug it in to find the other variable

6x+6(0)=-12

and solve for the last variable

6x+6(0)=-12

6x=-12

x=-2

thus

x=-2

y=0
