Question

solve all three please and show work for brainliest answer

1.
Solve the equation for b.
5a + 6b =2

2.
Solve the equation for r.
1 = prt

3. Solve the equation for x.
Ax+By=C

​

Answer 1

1.

5*a + 6*b =2

6*b = 2 - 5"a

b = (2-5*a)/6

2.

1 = p*r*t

r = 1/(p*t)

3.

A*x+B*y=C

A*x = C-B*y

x = (C-B*y)/A
