Answer :
Answer:
(6,-7)
Step-by-step explanation:
if you plug it in:
24-14=10
6+7=13
for the second one, if you have two minuses(6 - -7) you have to switch it to a plus sign (6+7)
hope this helps! :)
Here is how you would solve this system of equations.
[tex]\begin{bmatrix}4x+2y=10\\ x-y=13\end{bmatrix}[/tex]
Step 1: Multiply x-y=13 by 4.
[tex]\begin{bmatrix}4x+2y=10\\ 4x-4y=52\end{bmatrix}[/tex]
Step 2: Subtract the equations.
[tex]4x-4y=52[/tex]
-
[tex]\underline{4x+2y=10}[/tex]
[tex]-6y=42[/tex]
[tex]\begin{bmatrix}4x+2y=10\\ -6y=42\end{bmatrix}[/tex]
Step 3: Solve -6y=42
[tex]y=-7[/tex]
For 4x+2y=10 plug in y=-7
[tex]4x+2(-7)=10[/tex]
Simplify.
[tex]4x-14=10\\4x-14+14=10+14\\4x=24\\x=6[/tex]
Therefore, x=6, y=-7.
Hope this helps.
