Question

Solve this system of linear equations. Separatethe x- and y-values with a comma.X = 50 - 17y-15x = -36 + 17y

Answer 1

ok

x = 50 - 17y

-15x = -36 + 17y

I'll solve this problem by substitution

-15(50 - 17y) = -36 + 17y

-750 + 255y = -36 + 17y

255y - 17y = -36 + 750

238y = 714

y = 714/238

y = 3

x = 50 - 17(3)

x = 50 - 51

x = -1

Solution (-1, 3)
