5.find three solutions of the equation =7x=-5

The problem to solve is:

7x-5=9

First, let's work on the left hand side of your equation, the 7x-5
This means, for instance, to see if it can be simplified at all.
Multiply x and 7Multiply x and 1The x just gets copied along.The answer is xx7*x evaluates to 7x7*x-5 evaluates to 7x-5So, all-in-all, the left hand side of your equation can be written as: 7x-5Now, let's work on the right hand side of your equation, the 9
The right hand side of your equation can be written as: 9So with these (any) simplifications, the equation we'll set out to solve is:
7x-5 = 9
Move the -5 to the right hand side by adding 5 to both sides, like this:
To the left hand side:
-5 + 5 = 0The answer is 7xTo the right hand side:
9 + 5 = 14
Now, the equation reads:
7x = 14 
To isolate the x, we have to divide both sides of the equation by the other variables
around the x on the left side of the equation.
The last step is to divide both sides of the equation by 7 like this:
To divide x by 1The x just gets copied along in the numerator.The answer is x7x ÷ 7 = x14 ÷ 7 = 2The solution to your equation is:
x = 2The answer is 14
