the equation x/7+3=13
So by looking at this equation you know that you want to get x by itself. For starters you will need to multiply both sides 7*x/7+3=13*7 x+3=73 by seven so that the sevens on the left side will cancel each other out and it will leave youwith the equation x+3=73. Now
you will need to subtract 3 from both sides, so that the 3 on the left
side is canceled out and the 73 on the right side is reduced to a
70. thus leaving you with the equation x=70. So therefore the answer
to the equation is X=70. |

| Y=12x+b
(2, 12)
In this equation we are solving for b so that we can get the y-intercept. To start us of we need to punch the two pints into the equation in its correct spot.  Now
the equation looks liek this 12=12(2)+b. So we go ahead and begin
to work the problem out. 12=24+b, subtract 24 from both sides, 12=24+b
-24 -24 -12=b and thus it gives us -12=b, so the answer to the equation is Y=12x-12. |

To
solve the equation 5x-17=32-2x. First you are going to want to get
all the numbers to one side and the variable to the other. To start
it off add 17 to both sides.
5x-17=32-2x +17 +17 5x=49-2x. Now we are going to want to add 2x to both sides. 5x=49-2x +2x +2x 7x=49 Now we want to get x alone so we are going to divide
both sides by 7.
7x=49 x=7 7 7 |
