Add EF and DE together to equal 32
2x-10 + 4x = 32
Combine like terms;
6x-10 = 32
Add 10 to each side:
6x = 42
Divide both sides by 6:
x = 42/6
X = 7
EF = 2x-10 = 2(7)-10 = 14-10 = 4
DE = 4x = 4(7) = 28
The answer is 7 , You can just put it all in the calculator

Answer:
8 29/40
Step-by-step explanation:
(9 1/2 - 3 7/8) + (4 4/5 - 1 1/2)
9 1/2 - 3 7/8 = 5 5/8
4 4/5 - 1 1/2 = 3 3/10
5 5/8 + 3 3/10 = 8 29/40
