Answer:
(-2,-3)
Step-by-step explanation:
subtract -7y from both sides to get x = 7y + 19
plug in
5(7y + 19) = -2y - 16
distribute the 5
35y + 95 = -2y - 16
subtract 95 from both sides
35y = -2y - 111
add -2y to both sides
37y = -111
divide both sides by 37
y = -3
plug in the y to find the x
x = 7(-3) + 19
multiply 7 and -3
x = -21 + 19
subtract
x = -2
make into a coordinate
(-2, -3)
x - 7y = 19 multiply both sides by 5
5x - 35y = 95
Substitute 5x = -2y - 16:
(-2y - 16) - 35y = 95
(-2y - 35y) - 16 = 95 add 16 to both sides
-37y = 111 divide both sides by (-37)
y = -3
Put the volue of y to the first equation:
x - 7(-3) = 19
x + 21 = 19 subtract 21 from both sides
x = -2
