2/8- Quizizz- Equations

What is the goal of solving an equation with variables on both sides of the equal sign?

• Find a value of x that makes both sides of the equal sign equal to each other.

• To combine like terms on each side of the equal sign.

• Find a value of x that makes one side of the equation correct.

• To get a correct answer.

• To make an educated guess.

• Combining undefined and undefined to get undefined 

• Adding 7 to both sides of the equation.

• Subtracting 2 from both sides of the equation. 

In order to solve an equation, we must isolate the variable onto one side of the equation, and simplify the constants on the other side.

• True

• False

Jacob solved the following equation using the steps shown.

Step 1: 5x + 9 = 2x - 3

Step 2: 3x + 9 = -3

Step 3: 3x = -12

Step 4: x = -4

What operation did he perform to get from Step 1 to Step 2?

• Subtracted 2x from both sides of the equation

• Subtracted 9 from both sides of the equation

• Multiplied both sides of the equation by 3

• Added -3 to both sides of the equation

An equation is?

• a problem that contains variables, numbers and operations but no equal sign
