Math Skills

100

Explain how you know an equation has infinitely many solutions

What is when both sides are equal, when you can use any value for x and the equations balance

200

What makes an equation have no solution?

What is when you have same number of variables and different number of constants

300

What are the inverse operations?

What are using opposite operations to work backwards to solve equations

400

What is the difference between a two-step equation and a multi-step equation?

What is a two-step equation is two steps and a multi-step equation takes more than two steps?

500

Solve these three problems. 

-5(x+1) = -2x + 10

3(x+9)=12x+13

10 - 12(1-x) = 8(-12+6x)-14
