Question

a) 5/4(x+1)=10
b) 3y/5=21/50
solve​

Answer 1

Answer:

7

Step-by-step explanation:

5x + 5 / 4 = 10

5x + 5= 10 * 4 = 40

5x = 40-5

5x = 35

hence, x= 35/5

           = 7

7

Step-by-step explanation:

5

— (X+1) =10

4

5(X+1)=10x4

5x+5=40

5X=40-5

5x=35

35

X= —

5

X=7

B) 3y/5=21/50

cross multiply

50(3y)=21x5

150y=21x5

y=21x5/150

y=21/30
