-(-10)=a-[5+3a-{5a-(a+6)}]+13

- (- 10) = a - [5 + 3 a - {5 a - (a + 6)}] + 13

a = 4

Solution steps

- (- 10) = a - [5 + 3 a - {5 a - (a + 6)}] + 13

Switch sides

a - [5 + 3 a - {5 a - (a + 6)}] + 13 = - (- 10)

Apply rule

- (- a) = a

a - [5 + 3 a - {5 a - (a + 6)}] + 13 = 10

Move

13

to the right side

a - [5 + 3 a - {5 a - (a + 6)}] = - 3

Expand

a - (5 + 3 a - (5 a - (a + 6))) : 2 a - 11

2 a - 11 = - 3

Move

11

to the right side

2 a = 8

Divide both sides by

2

a = 4

\frac{3 c ^{9}}{( 3 c ) ^{2}}

4 y^{2} + 20 y + 25

21 (2 - x) + 12 x = 44

x^{2} - 36 \geq 0

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