What is the solution to the equation?
4(3 + 7) = 4 • x + 4 • 7

A. x = 3
B. x = 4
C. x = 7
D. x = 10

Answer 1

4(3+7)

so we need to do what's in the ( ) first

3+7 = 10

4(10) = 4x +28

Answer 2

40 = 4x+28

now how would you solve for x?

Answer 3

Subtract 4 from both sides?

Answer 4

we can subtract 28 from both sides

Answer 5

40-28 = 4x

so we get

12 = 4x

Answer 6

So would the answer be B?

Answer 7

divide 12/4
