Question 836687
y = -3x and 2x - 3y = 22
.
Using:
y = -3x
We "substitute" the value of 'y' with '-3x' (since they are equal) into:
2x - 3y = 22
2x - 3(-3x) = 22
2x + 9x = 22
11x = 22
x = 2  (answer for x)
.
Answer for y, we substitute the above into:
y = -3x
y = -3(2)
y = -6 (answer for y)
.
Solution: (x,y) = (2, -6)
