Does x satisfy the equation?

Front

What does it mean for a value to satisfy an equation?

Back

A value satisfies an equation if, when substituted for the variable, it makes the equation true.

Front

How do you determine if a value is a solution to an equation?

Back

Substitute the value into the equation and check if both sides are equal.

Front

What is the solution to the equation g - 3 = 7?

Back

g = 10.

Front

Is g = 11 a solution for g - 3 = 7?

Back

No, because 11 - 3 = 8, which does not equal 7.

Front

What is the solution to the equation s ÷ 4 = 5?

Back

s = 20.

Front

Is s = 24 a solution for s ÷ 4 = 5?

Back

No, because 24 ÷ 4 = 6, which does not equal 5.

Front

What is the solution to the equation x + 15 = 10?

Back

x = -5.

Front

Is x = -5 a solution for x + 15 = 10?

Back

Yes, because -5 + 15 = 10.

Front

What is the equation that is true if m = 19?

Back

m - 4 = 15.

Front
