ALL OF THESE WILL BE SOLVE FOR X AND Y!
Problem 1 Solve For x: x=-6y-7
Show work: Add - 6y to both sides.
x+6y+-6y=-7+-6y
x=-6y-7
Problem 1 Solve For y: y = - 1/6x + - 7/6
Show work: Add - x to both sides.
x+6y+-x=-7+-x
6y=-x-7
Step 2: Divide both sides by 6.
6y/6 = - x - 7/6
Problem 2 Solve For x: x=-6y-7
Show work: Add - 12y to both sides.
2x+12y+-12y=-14+-12y
2x=-12y-14
Step 2: Divide both sides by 2.
2x/2 = - 12y - 14/2
Problem 2 Sovle For y: y=-1/6x + - 7/6
Show work: Add - 2x to both sides.
2x+12y+-2x=-14+-2x
12y=-2x-14
Step 2: Divide both sides by 12.
12y/12 = - 2x-14/12
