Answer:
13. y = -4x + 6
14. y = 1/2x - 2
Step-by-step explanation:
You want to put y on one side and the rest of the numbers on the other side. You can do this by adding or subtracting or dividing the numbers/variables on the left.
13.
4x + y = 6
subtract both sides by 4x
y = 6 - 4x
or rewritten as:
y = -4x + 6
14.
-3x + 6y = -12
add both sides by 3x
6y = 3x - 12
divide both sides by 6
y = 1/2 x - 2
