Solve for X and Equivalent Equations

Front

What is an equivalent expression?

Back

An equivalent expression is one that has the same value as another expression for all values of the variable(s) involved.

Front

Solve for x: 28 + 3r = 10r

Back

x = 4

Front

Solve for x: 32 - 7x = -6(x + 3)

Back

x = 50

Front

Which expression is equivalent to -4(3x - 6) + 15x?

Back

3x + 24

Front

Solve for x: x + 23 = 58

Back

x = 35

Front

What is the first step in solving the equation 2x + 5 = 15?

Back

Subtract 5 from both sides to isolate the term with x.

Front

What does it mean to isolate a variable?

Back

To isolate a variable means to manipulate an equation so that the variable is on one side and all other terms are on the opposite side.

Front

What is the solution to the equation 5x - 10 = 0?

Back

x = 2

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a set of parentheses.

Front

Solve for x: 4(x - 2) = 16

Back

x = 6
