Use Pythagorean theorem.
I remember doing this but I forgot how.

Solve |2x - 5| = 4 if anyone could , that would be great

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

One number is 4 less than 3 times a second number. if 3 more than two times the first number is decreased by 2 times the second number, the result is 11. use the substitution method. what is the first number?
