HELP me solve my eq

Question

7a - 6 = -30 - 5a

I wanna learn how u do those.

TY Mr Dominus. ;)

Answer 1

7a - 6 = -30 - 5a

want to have numbers on right side and terms with variable "a" on left side

to get rid of -6 on left side, add 6 to both sides:

7a - 6 + 6 = -30 + 6 - 5a

7a + 0 = -24 - 5a

7a = -24 - 5a

to get rid of -5a on right side, add 5a to both sides:

7a + 5a = -24 -5a + 5a

12a = -24 + 0

12a = -24

to solve for a, divide both sides by 12, so a is left alone.

12a = -24

12 12

a = -2

Answer 2

First, write the original problem 7a-6=-30-5a

Then, add 6 to both sides7a-6+6=-30-5a+6

Next, combine like terms. The -6 and +6 cancel out and you are left with7a=-24-5a

Now, make sure both terms with a variable are on the same side. Do this by adding 5a to both sides .7a+5a=-24-5a+5a

At this point, you have both terms with the variable on the left and just the number on the right because the -5a and +5a cancel out7a+5a=-24

Now, combine like terms on the left side of the equation.12a=-24

Finally, divide both sides by 12 to get the a by itself.12a/12=-24/12

Your final answer is a=-24/12

a=-2

Answer 3

7a-6=-30-5a=

add 5a to both sides

7a-6+5a=-30

Combine 7a and 5x to get 12a.

12a-6=-30

Add 6 to both sides

12a=-30+6

Add-30 and 6 to get -24.

12a=-24

Divide -24 by 12 to get -2

a = -2
