Question 713449
█ Solve for x█

y=7-2x

Since x is on the right-hand side of the equation, switch the sides so it is on the left-hand side of the equation.
7-2x=y

Since 7 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 7 from both sides.
-2x=-7+y

Move all terms not containing x to the right-hand side of the equation.
-2x=y-7

Divide each term in the equation by -2.
-(2x)/(-2)=(y)/(-2)-(7)/(-2)

Simplify the left-hand side of the equation by canceling the common factors.
x=(y)/(-2)-(7)/(-2)

Simplify the right-hand side of the equation by simplifying each term.
x=(-y+7)/(2)

█ Solve for Y now █

y=7-2x

Reorder the polynomial 7-2x alphabetically from left to right, starting with the highest order term.
y=-2x+7
