Question

Solve the proportion 169=42x. A. x=3.429 B. x=74.6¯ C. x=23.625 D. x=362

Answer 1

You need to isolate the x which mean that you would remove the 42 from the right side. To do so you have to divide both sides by 42
169/42 = 42/42x
Now you have 169/42=x
Then do the division and you got your answer
