5x-4(-10)=20

5 x - 4 (- 10) = 20

x = - 4

Solution steps

5 x - 4 (- 10) = 20

Apply rule

- (- a) = a

5 x + 4 \cdot 10 = 20

Multiply the numbers:

4 \cdot 10 = 40

5 x + 40 = 20

Move

40

to the right side

5 x = - 20

Divide both sides by

5

x = - 4

\frac{1}{6} + \frac{2}{4}

6 (\frac{y + 1}{3}) + 7 y = 0

7 x^{2} - 56 = 0

- 1 < 3
