Solve in fraction form with a denominator of 100:

x + 3 = 6 2

A certain number, which first has 15 subtracted from it, then has the difference multiplied by 7, will give a result of 28. What’s the number?7(x – 15) = 287x – 105 =

28 7x = 133; x = 19Tell me the easier way to solve this

equationx – 15 = x – 15 = 4; x = 19

Be flexible, follow the path of least resistance.
