a^2x-a=4x-2

Solution

a^{2} x - a = 4 x - 2

Solution

x = \frac{1}{a + 2}; a \neq = 2, a \neq = - 2

Solution steps

a^{2} x - a = 4 x - 2

Move

a

to the right side

a^{2} x = 4 x - 2 + a

Move

4 x

to the left side

a^{2} x - 4 x = - 2 + a

Factor

a^{2} x - 4 x : x (a^{2} - 4)

x (a^{2} - 4) = - 2 + a

Divide both sides by

a^{2} - 4; a \neq = 2, a \neq = - 2

x = \frac{1}{a + 2}; a \neq = 2, a \neq = - 2

Popular Examples

3+x+2=2x-2(x-3)

3 + x + 2 = 2 x - 2 (x - 3)

(2x}{3+5}=\frac{8-5x)/2

\frac{2 x}{3 + 5} = \frac{8 - 5 x}{2}

-(-5x-5)-1=-(-9x+1)+6x

- (- 5 x - 5) - 1 = - (- 9 x + 1) + 6 x

- 9 x = 63

(2x-5)/5-3x=(20-3x)/2

\frac{2 x - 5}{5} - 3 x = \frac{20 - 3 x}{2}
