Morgan solved the following equation. equation: 22 - 4) + 2x = x + 7
2x – 8 + 2x = x +7
line 1:
line 2:
4x – 8 = x +7
line 3:
3x – 8 = 7
line 4:
3x = 15
line 5:
x = 5
Which step is justified by the addition property of equality?

A. From the equation to line1
B. From line 1 to line 2
C. From line 3 to line 4
D. From line 4 to line 5

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

2/4 is the answer

step-by-step explanation:

x= total pieces

both ate 9 pieces

mindy ate 3 so troy ate 6

6= (1/4)x

x =24

if e is the midpoint of bd, then bd is 14.
