4 (18-x) = 32.8

4 (18-x) = 32.8


18-x=32.8÷4
18-x=8.2
x=18-8.2
x=9.8



Solution equation: X (X-7) = 8 (7-x)
Solving quadratic equation of one variable


X (X-7) - 8 (X-7) = 0 (X-8) (X-7) = 0, x = 8 or 7,



7 / 8-x = 1 / 2, solve the equation


7 / 8-x = 1 / 2
x=7/8-1/2
x=3/8



Solving equation x (X-7) = 8 (X-7)


X1=7
X2=8
