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 7 Multiply x and 1 The x just gets copied along. The answer is x x 7*x evaluates to 7x 7*x-5 evaluates to 7x-5 So, all-in-all, the left hand side of your equation can be written as: 7x-5 Now, 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 = 0 The answer is 7x To 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 1 The x just gets copied along in the numerator. The answer is x 7x : 7 = x 14 : 7 = 2 The solution to your equation is:

x = 2 The answer is 14
