Solve an equation x^2-7/3x-2=0
A:
(x^2-7)/(3x-2)=0
So:
x^2-7=0
x^2=7
X = √ 7 or x = - √ 7
It is the root of the original fractional equation
7 / 6x = 3 / 1.8
18x = 1.8 times 7
x=0.7
6.3 △ x equals seven equations
x=0.9
Two out of nine divided by 18 is one out of six
18÷(2/9) = x/6
18÷2*9 = x/6
9*9 = x/6
x = 81*6
x = 486
