Solving "1 Step" Equations:
My Question will be x+9=14
Step one: Isolate the Variable
To do this you have to get rid of the constant using a zero pair.
EXAMPLE:
x+9-9=14
Step 2: Once you have done that you must do the same to the answer to keep them even.
EXAMPLE:
x=14-9
Step 3: Then you have to Verify or check your answer by plugging that number into the question.
EXAMPLE:
x=5
x+9=14
5+9=14
14=14
Now I will solve it using algebra tiles:
Let x equal green always
Let 1 be red always
Let -1 be white always
Solving "2 Step" Algebra Equations:
My question will be 3x+4=19
Step one: Isolate the Variable
To do this you have to get rid of the constant using a zero pair.
EXAMPLE:
3x+4-4=19
Step 2: Once you have done that you must do the same to the answer to keep them even.
EXAMPLE:
3x=19-4
Step 3: Simplify the Variable
EXAMPLE:
3x=15
3x/3=15/3
x=5
Step 4: Then you have to Verify or check your answer by plugging that number into the question.
EXAMPLE:
3x+4=19
3(5)+4=19
15+4=19
19=19
Now I will solve it using algebra tiles:
Let x equal green always
Let 1 be red always
Let -1 be white always
