1 is BD
2 is 15
3 is y = 2
4 is 40
5 is 47
1) BD

2) 
3x = 5x - 10
2x = 10
x = 5

GH = 5x - 10 = 5(5) - 10 = 15
answer: 15

3)
10y = 8y + 4
2y = 4
y = 2
answer: 2

4)
m<DBE = 2(8y+4)
m<DBE = 2(8*2  + 4)
m<DBE = 2(20)
m<DBE = 40
Answer
m<DBE = 40

5)
m<FBA = 7x+6y 
m<FBA = 7(5) + 6(2)
m<FBA = 35 + 12
m<FBA =47

answer
m<FBA = 47
