Answer:
x=3/2y−6
y=2/3x+4
Step-by-step explanation:
Let's solve for y.
12=−2x+3y
Step 1: Flip the equation.
−2x+3y=12
Step 2: Add 2x to both sides.
−2x+3y+2x=12+2x
3y=2x+12
Step 3: Divide both sides by 3.
3y/3=2x+12/3
Answer:
y=-x-0.833.....
Step-by-step explanation:
You solve for Y in the first two and then solve for x in the last two parts of the problem.
