b = -30
Step-by-step explanation:
we have to solve the given equation to get the value of b.
The equation is a linear equation
Given
[tex]\frac{2}{5}b+1 = -11[/tex]
Subtracting 1 from both sides
[tex]\frac{2}{5}b+1-1 = -11-1\\\frac{2}{5}b =-12[/tex]
Multiplying both sides by 5
[tex]2b = -12*5\\2b = -60[/tex]
Dividing both sides by 2
[tex]\frac{2b}{2} = -\frac{60}{2}\\b = -30[/tex]
Hence,
b = -30
