Solve equations involving like terms
Key notes:
Like terms are terms that have the same variables raised to the same powers. To subtract like terms, subtract their coefficients.
Learn with an example
➡️ Solve for b.
11b − 2b = 9
b =______
Combine the b terms:
11b − 2b = 9
9b = 9
Divide by 9 to solve for b:
9b/9 = 9/9
b = 1
The answer is 1.
➡️ Solve for m.
m + 6m = 7
m =_______
m is the same as 1m.
Combine the m terms:
m + 6m = 7
7m = 7
Divide by 7 to solve for m:
7m/7 = 7/7
m = 1
The answer is 1.
➡️ Solve for j.
12j − 4j = 16
j =______
Combine the j terms:
12j − 4j = 16
8j = 16
Divide by 8 to solve for j:
8j/8 = 16/8
j = 2
The answer is 2.
