Can you help me write these out in an algebraic expression?

Question

1. Seven less than twice a number equals 19.

2.Eight decreased by 3 times a number equals 2.

3. The sum of two times a number and 5 is 11.

Is this right?
x/8 + -1/2 = 6

My answer: x=44

Answer 1

no. Add 1/2 to each side
x/8=6.5
multiply both sides by 8
x=52
