Grade 8 Illustrative Math Unit 4 Lesson 1 - 8

Front

Solve for x: 2x -1(3+4x) = 11

Back

x = -7

Front

What is the first step to solve this equation: - 3x -11 = 44

Back

Add 11 to both sides

Front

Simplify each equation. Tell whether the equation has one, no, or infinite solutions: 3x - 8 = 3(x - 4) + 1

Back

no solutions

Front

What operation would you perform first and then second when solving for m in the following equation? 10 + 7m = 17

Back

subtract 10, divide by 7

Front

Solve: 3x + 15 = 3(x + 5)

Back

Infinitely Many Solutions

Front

What does it mean if an equation has no solutions?

Back

It means there are no values of the variable that satisfy the equation.

Front

What is the distributive property?

Back

a(b + c) = ab + ac

Front

What is the first step in solving the equation 5x + 3 = 18?

Back

Subtract 3 from both sides.

Front

What does it mean if an equation has infinitely many solutions?

Back

It means that any value of the variable will satisfy the equation.

Front

What is the purpose of isolating the variable in an equation?

Back

To find the value of the variable that makes the equation true.
