Answer 1

x = -7

Answer 2

5x+45=10
5x=-35
x=-7

Answer 3

Distributive property:
5x + 45 = 10
5x = -35
x = -7

Answer 4

use distributive property
\[5x+45=10\]
\[5x=10-45\]
\[5x=-35\]
\[x=-35/5\]
\[x=-7\]

Answer 5

Simplifying
5(x + 9) = 10

Reorder the terms:
5(9 + x) = 10
(9 * 5 + x * 5) = 10
(45 + 5x) = 10

Solving
45 + 5x = 10

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-45' to each side of the equation.
45 + -45 + 5x = 10 + -45

Combine like terms: 45 + -45 = 0
0 + 5x = 10 + -45
5x = 10 + -45

Combine like terms: 10 + -45 = -35
5x = -35

Divide each side by '5'.
x = -7

Simplifying
x = -7
