There is a number.Three times the number minus 6 is equal to 45. find that number.

Answer 1

3x-6 = 45

solve the equation by opposite of PEMDAS

in this case first focus on canceling -6

since 6 is the opposite of -6, add 6 to both sides

3x-6+6 = 45+6

3x = 51

since opposite of multiplication is division;

divide both sides by 3 and find the answer
