Front

What are like terms in algebra?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3a and 5a are like terms, while 3a and 4b are not.

Front

How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that are alike. For example, in the expression 5a + 2a, you combine them to get 7a.

Front

What is the process to solve a linear equation?

Back

To solve a linear equation, isolate the variable on one side of the equation by performing inverse operations (addition, subtraction, multiplication, division) on both sides.

Front

Solve: 5a + 2b - 3a + 4 = ?

Back

2a + 2b + 4

Front

Solve: 14y + 5 = 8y - 1. What is y?

Back

y = -1

Front

Combine like terms: n - 10 + 9n - 3 = ?

Back

10n - 13

Front

Solve: 4k + 39 = 7k + 6. What is k?

Back

k = 11

Front

Solve: 46 - 8p = 19 + p. What is p?

Back

p = 3

Front

What is a coefficient in algebra?

Back

A coefficient is a numerical factor in a term of an algebraic expression. For example, in 4x, 4 is the coefficient.

Front

What is a variable in algebra?

Back

A variable is a symbol, often a letter, that represents a number in mathematical expressions or equations. For example, in the expression 3x + 2, x is the variable.
