Use your skills for solving one-step and two-step equations to SOLVE math problems 1-4.
Remember: SOLVE means to calculate a final number answer for the variable or letter.
Pro-Tip: Write each equation on paper and do your work on paper.
Question 1
1.
Solve.
Question 2
2.
Solve.
Question 3
3.
Solve.
Question 4
4.
Use your skills for simplifying expressions to SIMPLIFY the expressions in numbers 5-9.
Remember: SIMPLIFY means to make your expression shorter or easier to solve.
Watch the video below to refresh your memory on how to simplify expressions by combining like terms..
Question 5
5.
Simplify (do not use spaces):
