4x+7x-40=60-9x

4 x + 7 x - 40 = 60 - 9 x

x = 5

Solution steps

4 x + 7 x - 40 = 60 - 9 x

Add similar elements:

4 x + 7 x = 11 x

11 x - 40 = 60 - 9 x

Move

40

to the right side

11 x = - 9 x + 100

Move

9 x

to the left side

20 x = 100

Divide both sides by

20

x = 5

3 x^{2} - 7 x - 5 = x^{2} + 7 - 5 x

∣ x + 7 ∣ > 3

\frac{2}{3} (x - 6) = \frac{3}{4} (x + 16)

5 x^{4} - 30 x^{2} - 135

16 - 2 r = - 3 r + 6 r + 1
