Solving multi-step problems using non-linear equations in one variable

LET'S TRY ONE!!

2X+4=10

WHAT IS THE SECOND STEP THAT WE WILL DO ?

• SUBTRACT 2 FROM BOTH SIDES

• ADD 2 TO BOTH SIDES

• DIVIDE BY 2 ON BOTH SIDES

States that the two sides of an equation remain equal when you add the same number to each side

• Addition Property of Inequality

• Addition Property of Equality

• Step 1 and Step 2

• Step 2 and Step 3

• Step 3 and Step 4

• Step 4 and Step 5

In order to get the variable by itself in 3x=99. I have to __________ each side by 3.

• multiply

• add

• divide

• subtract

What property of equality is shown below?

y - 12 = 30

y -12 + 12 = 30 +12

• addition property of equality

• subtraction property of equality

• multiplication property of equality

• division property of equality

The inverse operation of multiplication is ​ (a)   .

• division
• subtraction
• pre-algebra
• exponents
• square root

What goes in line 4 of the reasons?

• Subtraction POE

• Division POE

• Distributive Property

What is the second step to the following equation?

-2 - 4x = -14

• Divide by negative four on both sides

• Multiply by negative four on both sides

• Add two to both sides

• Subtract fourteen from both sides

What is the first step in solving for a variable?

• Use inverse operations to undo operations and isolate the variable.

• Identify the operations on this variable and the order in which they are applied.

• Locate the variable you are asked to solve for in the equation.

• 

What should the SECOND step be in solving the equation  $\frac{x}{-4}+10=-12$ ? 

• Subtract 10 from both sides

• Add 10 from both sides

• Multiply -4 to both sides

• Divide by -4 to both sides
