simplify 3x-(6x+1)+(x-3)

simplify

3 x - (6 x + 1) + (x - 3)

- 2 x - 4

Solution steps

3 x - (6 x + 1) + (x - 3)

Apply rule:

a + (b + c) = a + b + c

- (6 x + 1) + (x - 3) = - (6 x + 1) + x - 3

= 3 x - (6 x + 1) + x - 3

Group like terms

= - (6 x + 1) + 3 x + x - 3

Add similar elements:

3 x + x = 4 x

= - (6 x + 1) + 4 x - 3

Apply the distributive law:

- (a + b) = - a - b

- (6 x + 1) = - 6 x - 1

= - 6 x - 1 + 4 x - 3

Group like terms

= - 6 x + 4 x - 1 - 3

Add similar elements:

- 6 x + 4 x = - 2 x

= - 2 x - 1 - 3

Subtract the numbers:

- 1 - 3 = - 4

= - 2 x - 4

\frac{a}{b ^{2} + ab} - \frac{b}{a ^{2} + ab}

4 \cdot 4 \cdot 4 \cdot 4 \cdot 4 \cdot 4

4 + \frac{1}{4} - \frac{1}{8} - (1 - (3 \frac{1}{2} + 1.6))

\frac{2 e ^{- x}}{e ^{x}}

5 0^{2} + 5 0^{2}
