Question

Drag each equation to show if it could be a correct first step to solving the equation 8(x + 5) = 56.

Answer 1

8(x + 5) = 56

first step id to distribute the 8 through the parenthesis

8x + 40 = 56

Answer 2

Distribute 8 to all terms within the parenthesis

Explanation:

Remember to follow PEMDAS. The steps are:

1) Distribute 8 to all terms within the parenthesis

8(x + 5) = 8(x) + 8(5) = 8x + 40

2) Isolate the x. Do the opposite of PEMDAS

8x + 40 = 56

2.5) Note the equal sign. What you do to one side, you do to the other

8x + 40 (-40) = 56 (-40)

8x = 56 - 40

8x = 16

(8x)/2 = (16)/2

x = 16/2

x = 8

8 is your answer
