Question

solve this system of linear equations, separate the x- and y-values with a comma. -4x=-60-19y -7x=-48-19y

Answer 1

The solution is at (-4,-4).

Explanation:

(-4x=-60-19y)-1 Multiply by -1

4x = 60 + 19y

-7x = -48 - 19y Add both equations together

-3x = 12 Divide both sides by -3

x = -4

Plug this into the first equation to find the value of y

-4(-4) = -60 - 19y Multiply

16 = -60 - 19y

+60 +60 Add 60 to both sides

76 = -19y Divide both sides by -19

y = -4
