I'll show you a solution, on one condition: That you get together with your teacher
or an adult who's OK at math, and get some help in simple algebra. Your question
shows that you need it.
Deal ?
OK then . . .
4b - 100 = -b
Add 'b' to each side of the equation:
5b - 100 = 0
Add 100 to each side :
5b = 100
Divide each side by 5 :
b = 20
b = Ah divide both sides by A b/A = h

(1) Add the two equations together & solve for A:A - B = 381A + B = 561-------------------2A + 0B = 9422A = 9422A/2 = 942/2A = 471(2) Now substitute A back into one of the original equations & solve for B:A + B = 561471 + B = 561B = 561 - 471B = 90
36 -20 = 16
It is not possible to solve a single linear equation in two unknown variables (b and t).
b = Ah divide both sides by A b/A = h
b = y - mx.
b=Ah

root 7
x=b-a
c equals b over 8
If: a = b+c+d Then: c = a-b-d
