Intro to Equations

What is the key strategy for solving equations with an unknown value?

• Adding the same number to both sides

• Guessing the value of the unknown

• Isolating the unknown on one side of the equation

• Multiplying both sides by the highest number

How do you solve an equation where the unknown is being multiplied by a number?

• Multiply both sides by the same number

• Divide both sides by the same number

• Subtract the number from both sides

• Add the same number to both sides

What should you do if an unknown is being divided by a number?

• Multiply both sides by the number

• None of the above

• Divide both sides by the number

• Subtract the number from both sides

What is the result of solving the equation x/10 = 15?

• x = 0.15

• x = 15

• x = 150

• x = 1.5

In the equation 4/x = 2, what is the first step to isolate x?

• Divide both sides by 2

• Multiply both sides by 4

• Subtract 2 from both sides

• Multiply both sides by x
