THE GIVEN EXPRESSION IS:

+2%2F5+=+%28x-2%29%2F20+

SIMPLYING IT FURTHER WE GET:

2 * 20 = 5(X - 2)

40 = 5X - 10

5X = 40 + 10

5X = 50

X = 50%2F10

X = 5

THUS THE SOLUTION.

2%2F5=%28x-2%29%2F20 Start with the given ratio


%282%2F5%29%2A20=x-2 Multiply both sides by 20


40%2F5=x-2 Multiply


8=x-2 Reduce


10=x Add 2 to both sides



So our answer is x=10
