Question

Solve the equation 3/2 + b = 7/4 what's b?

Answer 1

The answer is 1/4.

Answer 2

For this case we must find the value of "b" of the following equation:

`\frac {3} {2} + b = \frac {7} {4}`

Then, we subtract
`\frac {3} {2}` from both sides of the equation:

`\frac {3} {2} - \frac {3} {2} + b = \frac {7} {4} - \frac {3} {2}\\b = \frac {7} {4} - \frac {3} {2}\\b = \frac {14-12} {8}\\b = \frac {2} {8}\\b=(1)/(4)`

Answer:

`b = \frac {1} {4}`
