Answer:
x = 3
Step-by-step explanation:
1) Substitute -3 for y in the equation:
-3x - 5(-3) = 6
2) Simplify, two negatives multiplied equals a positive.
-3x + 15 = 6
3) Solve for x, first subtract 15 from both sides
-3x - 15 + 15 = 6 - 15
-3x = -9
4) Solve for x, divide both sides by - 3
-3x/-3 = -9/-3
x = 3
