# Find the value(s) of x in each proportion: a) x 6 = 3 x c) 6 x + 4 = 2 x + 2 b) x − 5 3 = 2 x − 3 7 d) x + 3 5 = x + 5 7 e) x − 2 x − 5 = 2 x + 1 x − 1 g) x − 1 x + 2 = 10 3 x − 2 f) x ( x + 5 ) 4 x + 4 = 9 5 h) x + 7 2 = x + 2 x − 2

To determine

a)

To find:

The value of x in proportion.

Explanation

Property used (Mean-Extremes Property):

In a proportion, the product of the means equal to the product of the extremes, that is, if aâ€‰bâ€‰=cd(Whereâ€‰bâ‰ 0Â andÂ dâ‰ 0)

Then aâ‹…d=bâ‹…c

Calculation:

Given, xâ€‰<
