|4-x|=3

∣ 4 - x ∣ = 3

x = 1 or x = 7

Solution steps

∣ 4 - x ∣ = 3

Apply absolute rule: If

∣ u ∣ = a, a > 0

then

u = a

u = - a

4 - x = - 3 or 4 - x = 3

4 - x = - 3 or 4 - x = 3

x = 1 or x = 7

3 x^{2} - x + 6 = 0

5 (2 - x) - x = 2 (x + 1)

\frac{x + 1}{3} + \frac{x}{5} = \frac{x + 1}{2}

\frac{( 9 b ^{2} + 33 b - 18 )}{( b + 4 )}
