Q:
# y=-8x β 37x+3y=4Substitution method

Accepted Solution

A:

Answer:(- 5, 3 )Step-by-step explanation:Given the 2 equationsy = - 8x - 37 β (1)x + 3y = 4 β (2)Substitute y = - 8x - 37 into (2)x + 3(- 8x - 37) = 4 β distribute and simplify left sidex - 24x - 111 = 4- 23x - 111 = 4 ( add 111 to both sides )- 23x = 115 ( divide both sides by - 23 )x = - 5Substitute x = - 5 into (1) for corresponding value of yy = - 8(- 5) - 37 = 40 - 37 = 3Solution is (- 5, 3 )
