##### 3 Answers

See a solution process below:

#### Explanation:

First, combine like terms on the left side of the equation:

Next, subtract

Now, divide each side of the equation by

#### Explanation:

Transposing the terms and adding like terms gives us,

#### Explanation:

#"collect terms in x on the left side of the equation and"#

#"numeric values on the right side"#

#rArr5+8x=-3#

#"subtract "5" from both sides"#

#cancel(5)cancel(-5)+8x=-3-5#

#rArr8x=-8#

#"divide both sides by "8#

#(cancel(8) x)/cancel(8)=(-8)/8#

#rArrx=-1#

#color(blue)"As a check"# Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

#5-1-7=-3=" right side"#

#rArrx=-1" is the solution"#
