all the possible solutions:
choose a method:
substitution, graphing, elimination
Operation to get the x variables to cancel
divide the bottom equation by 2
multiply the bottom equation by x2
mulitply the top equation by x-2
divide the top equation by 4
simplified top equation
-6x+4y=96
x+2y=46
-6x-8y=-96
3x+7=30
after adding the equations
8y-96
-6y=-36
6y=-96
-8y=-96
solve for x and y
y=-12
x=6
y=18
x=-3
1 answer
To get the x variables to cancel out, you would multiply the top equation by -2.
After completing step 2, the top equation would be -6x+4y=96.
After adding the equations together, you would get -6y=36.
Solving for y, you would find y=-6.
Finally, solving for x, you would substitute the value of y into one of the original equations. Using the first equation, you would get 3x+4(-6)=48. Simplifying, you would get 3x-24=48. Solving for x, you would get x=24/3=8.
Therefore, the solution to the system of equations is x=8 and y=-6.
