What is the value of the expression when a = 5 and b =2? a = 2b - 3 a.6 b.9 c.11 d.24

First you substitute the varibles with the correct number which would be 5=2(2)-3

Then you solve for it and your answer should be A. but I'm not a 100% sure because the sides do not equal

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
