Solve this system of linear equations. Separate
the x- and y-values with a comma.
-5x + 3y = 13
7x + 2y = -12

x = -2, y = 1

Step-by-step explanation:

So you can solve this equation using subtraction.

Multiply the first equation by 2:

-10x + 6y = 26

Multiply the second equation by 3:

21x + 6y = -36

Subtract the two equations:

-31x = 62

x = -2

y = 1

the answer will be b x² +x-1

step-by-step explanation:

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
