Answer:
y=2x-3
Step-by-step explanation:
2x-y=3
-2x on both sides of the equal sign which leaves you with -y=-2x+3
divide both sides by negative 1
y = 2x -3
to solve for y, simply isolate the y so in this case move 2x to the right side of the equation in which it becomes -y= -2x +3 and then divide by -1 which is beside the -y essentially cause y cannot be negative so then the equation becomes y = 2x -3
-3(2x-6)+4=-6x+18+4=-6x+22
