Question

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

Answer 1

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:

$\frac {3} {2} - \frac {3} {2} + b = \frac {7} {4} - \frac {3} {2}\\b = \frac {7} {4} - \frac {3} {2}\\b = \frac {14-12} {8}\\b = \frac {2} {8}\\b=\frac{1}{4}$

Answer:

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

Answer 2

Answer:

The answer is 1/4.
