Answer:
Explanation:
EG = EF + FG
10x - 8 = 5x - 2 + 3x + 4
10x - 8 = 5x + 3x - 2 + 4 {Combine like terms}
10x - 8 = 8x + 2
Add 8 to both sides
10x = 8x + 2 + 8
10x = 8x + 10
Subtract 8x from both sides
10x - 8x = 10
2x = 10
Divide both sides by 2
x = 10/2
x = 5
EG = 10x - 8
= 10*5 - 8
= 50 - 8
EG = 42
