3/4 x+7=x+4

\frac{3}{4} x + 7 = x + 4

x = 12

Solution steps

\frac{3}{4} x + 7 = x + 4

Move

7

to the right side

\frac{3}{4} x = x - 3

Move

x

to the left side

- \frac{1}{4} x = - 3

Multiply both sides by

- 4

x = 12

2 x^{2} + 15 x - 27 = 0

- \frac{3}{4} ∣ x - 3 ∣ = \frac{1}{4}

9 x^{2} + 48 x + 68 = 0

4 x^{3} + 6 x^{2} - 40 x

4 x^{2} + 12 x + 9 = 169
