There is a problem in the student's steps he took to solve the problem show to you on the left. He knows the solution is x = 1, but doesn't why not getting the right answer. identify the problem.

• There is no problem his steps are okay.

• There is a problem on the way he applied the distributive property

• There is an error of omission of a negative on 5 after applying a distributive

• I Think the problem is with the question itself he needs to check the question and do again.

When you add a number to each side of an equation, you are using the ___________.

• Addition Property of Equality

• Subtraction Property of Equality

• Multiplication Property of Equality

• Division Property of Equality

Solve -2w + 10 = 56

• 23

• -23

• 33

• -33

Solve  9 - 5t  = 24

• t = -3

• t = 3

• t = -6.6

• t = 12

3y+6+4y-7=-8

• y=-1

• y=-8

• y=1

• y=7
