The answer is 13/12. First you add -7/4 to both sides to isolate the variable(b) which would then create b = -2/3 + 7/4. Solve that to get 13/12

Answer:

b = 13/12

Step-by-step explanation:

[tex]b-\frac{7}{4} =-\frac{2}{3} \\\\\\b=-\frac{2}{3} + \frac{7}{4} \\\\\\b =-\frac{8}{12} + \frac{21}{12}\\ \\\\b=\frac{13}{12} \\[/tex]
