Solve the following equation for x.
m (2-x)=3-y

 m=−y+3−x+2

x=2m+y−3m

Step-by-step explanation:  

m(2−x)=3−y

Step 1: Factor out variable m.

m(−x+2)=−y+3

Step 2: Divide both sides by -x+2.

m(−x+2)−x+2=−y+3−x+2

m=−y+3−x+2

m(2−x)=3−y

Step 1: Add -2m to both sides.

−mx+2m+−2m=−y+3+−2m

−mx=−2m−y+3

Step 2: Divide both sides by -m.

−mx−m=−2m−y+3−m

x=2m+y−3m

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
