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

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

no. Add 1/2 to each side

x/8=6.5

multiply both sides by 8

x=52

1. Seven less than twice a number equals 19

2n - 7 = 19

2.Eight decreased by 3 times a number equals 2

8 - 3n = 2
