solve the follwing formulas for the indictaed variable?

Question

1. for a solve1/a+1/b=1/c
2. for x solve y=-3x+2
3. for s solve 2=(x-m)/5

4. for s solve z=(x-m)/5

Answer 1

1. for a solve1/a+1/b=1/c
2. for x solve y=-3x+2
3. for s solve 2=(x-m)/5

1) multiply by a*b*c
(abc)/a + abc/b = abc/c

bc + ac = ab
ab - ac = bc
a(b-c) = bc
a = bc/(b-c)


2) y = -3x + 2
y - 2 = -3x
3x = (2-y)

x = (2-y)/3


3) 2=(x-m)/5
10 = x-m

10 + m = x

m = x-10

Answer 2

1. for a solve1/a+1/b=1/c
1/a = 1/c - 1/b = (b-c)/(bc)
a = bc/(b-c)

2. for x solve y=-3x+2
3x = 2-y
x =(2-y)/3

3. for s solve 2=(x-m)/5
There is no s. I assume you mean x.
10 = x-m
10+m = x
