Learn to solve two step equations.
Solving two step equations.
When solving a two-step equation you will need to perform two steps in order to solve the equation.
When solving a two -step equation you want only variables on one side of the equal sign and numbers on the other side of the equal sign.
In addition the number in front of the variable needs to be equal to one.
Remember when solving a linear equation, whatever you do to one side of the equation, you must do to the other side of the equation.
Let's look at some example problems
Let's solve these two step equations.
Step 1 is that we want to go ahead and get the variable isolated.
We first we will eliminate the 3 and we undo the addition with subtraction.
What we do to one side we must perform to the other side.
The 3's cancel and we are left with 6 and v over 11 on the other side.
Now we need to undo the division with multiplication, so multiply each side by 11 and the 11 cancels and that leaves us with v = 66
Next we have 7p + 2 = 23.
We first need to get the p by itself, or at least a 1 in front of the p
We can do that by undoing the addition with subtraction.
We will subtract 2 from both sides and we cancel and 23 minus 2 = 21
Bring 7p down.
In order to get rid of the multiplication we will need to divide both sides by 7
7 divided by 7 = 1, and 21 divided by 7 = 3
So the final answer is p = 3
Finally, our last one is similar to the one we just completed and that is 5m+5=75
We will undo the subtraction by subtracting 5 from each side.
75 - 5 = 70
Bring the 5m down
We will get rid of the multiplication with division.
We are left with m, actually there is a 1 in front of the m
70 divided by 5 = 14
There we go
Hope this helps with two step equations.
