Solving equation (30-2x) (20-2x) = 300

Solving equation (30-2x) (20-2x) = 300


Simplify to x ^ 2-25x + 75 = 0; use the root formula



3 / 2 [2 / 3 (x-1 / 5) - 2] - 2x = 3 solution


y=96-x
1/x+1/(96-x)=1/18
18(96-x+x)=x(96-x)
x²-96x+1728=0
(x-72)(x-24)+0
x=72,x=24
y=96-x
therefore
x=72,y=24
x=24,y=72



2x-6 = 12 to solve the equation


2x=12+6
2x=18
x=9



6 + 2x = 12, solve the equation


2x=12-6
2x=6
x=6÷2
x=3
