lists the steps you would take to solve for the variable?

Question

5a+5=90

Answer 1

5a + 5 = 90
5a = 90 - 5
5a = 85
a = 85/5
a = 17

Answer 2

1.You try to get the variables(a) on the left and the numbers on the right!So you do th einverse operation so you subtract 5 from both sides to make that happen!
2.After the variables are on the left and the numbers are on the right you do the inverse operation! if it looks like a=1 you divide cause this is a multiplication promblem!if it looks like a/1 you multiply because this is a division promblem!your answr should look like 5a=85!So you divide each side by 5!the 5 cancels out on the left so you just divide it out on the right!
3.you should have a solution of x= or variable =!
your answer should look like.....
5a+5=90
-5 -5
5a=85
5a 5
a=17

Answer 3

In this type of question, solving for the variable is just finding out what it is equal to. In order to do that, you need to get it by itself on one side of the equation. The great thing about algebra is that you can perform operations to both sides to maintain equality. For example, start by subtracting 5 from both sides.

5a+5=90
5a+5-5=90-5
5a=85

Then you can perform a division operation to determine the value of a:

5a = 85
5a/5 = 85/5
a = 17

Answer 4

First: isolate "5a" on one side --- subtract "5" from both sides (when you move a term to the opposite side, always use the opposite sign).....

5a + 5 - 5 = 90 - 5

5a = 85

Sec: isolate the "a" variable on one side by itself --- divide both terms on either side with "5"...

5a/5 = 85/5

a = 17

Answer 5

5a+5=90
5a=85 (subtract 5 from both sides)
a=17 (divide both sides by 5)
