My daughter needs to solve 3x + 5 = 20 and show the work.
Here is an example of one problem she completed in class:
5x - 10 = 20 <<< Get the term containing x all by itself on one side of the equation.
+10 = +10 <<< She added 10 to both sides to eliminate the -10 from the left side.
5x.....= 30 <<< I would add this step which is the result of the previous addition.
5x/5 = 30/5 <<< We divide by the coefficient of the variable to get one x. (5 of 'em divided by 5 quals one of em).
....x = 6 <<<(5x/5=x and 30/5=6)
20 30 / 5 <<< I don't know what the 20 is.
