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
multiply both sides by 8

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
