Mathematics
1 answer:
kozerog [31]2 years ago
4 0

Answer:

\frac{b-7}{b+1}=\frac{b-10}{b+4}

\left(b-7\right)\left(b+4\right)=\left(b+1\right)\left(b-10\right)

\left(b-7\right)\left(b+4\right)=b^2-3b-28

\left(b+1\right)\left(b-10\right)=b^2-9b-10

b^2-3b-28=b^2-9b-10

b^2-3b-28+28=b^2-9b-10+28

b^2-3b=b^2-9b+18

b^2-3b-\left(b^2-9b\right)=b^2-9b+18-\left(b^2-9b\right)

6b=18

\frac{6b}{6}=\frac{18}{6}

b=3

Easy if you know the formula

all this means is that your x value is a, and when it is, will give you the value 26.

f(a) = 6a - 4 = 26

6a = 30
a = 5
