Thank you whoever answers this!

Can someone summarize the steps to solve this equation in 3 steps? I'm already aware of what x and y are equal too, but I need to summarize the steps of solving equation:

-3x-4y= -2
y=2x-5​

Answer:

x=2 and y=-1. The steps--

Step-by-step explanation:

FIRST STEP: SUBSTITUTE -4y with the definition in y=2x-5. This makes the first equation -3x-4(2x-5)=-2

SECOND STEP: DISTRIBUTE -4 throughout the parenthesis, making the equation -3x-8x+20=-2.

LAST STEP: SOLVE by combining like terms, -3x-8x, to make -11x, and subtracting 20 from each side, to make -11x=-22. Then divide both sides by -11, making x=2. From there, you solve that y=2(2)-5, solving that y=4-5, y=-1.

Therefore, x=2 and y=-1
