Question #4064

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

Expert's answer

1. 2x - 7 = 19 x = 13

2. 8 - 3x = 2 x = 2

3. 2x + 5 = 11 x = 3

x/8 + -1/2 = 6

x/8 - 0.5 = 6

x/8 = 6.5

x = 6.5* 8 = 52

2. 8 - 3x = 2 x = 2

3. 2x + 5 = 11 x = 3

x/8 + -1/2 = 6

x/8 - 0.5 = 6

x/8 = 6.5

x = 6.5* 8 = 52
