Question

HELP PLZ!!!!! im taking a quiz and dont know how to do it...
solve this system of linear equations. seperate the x- and y-values with a comma.
-4x+2y=12
-13x+3y=46

Answer 1

Now so far take a look at this, we can solve this equation by substitution.

say we take the top equation:

we can solve for y

2y = 12+4x

divide both sides by (2)


Now we've got an expression for y.


y = 6 + 2x

Answer 4

@pig_cat223 try to solve for y in this equation: follow through what I did

-4x+2y = 12

Answer 5

plug in the y into the 2nd equation

Answer 6

for first step ur trying to get y by itself
