1.

Solve m-n = 5 for m.

I a) m = 5+n

b) m = - 5 -

c) m = - 5+n

d) m = 5 -

2.

Solve - 2 = 4r + s for s.

a) s = - 2 + 41

b) s = 2 - 4r

d) s = 2 + 4r

Ar

Step-by-step explanation:

we can solve:

Solve m-n = 5 for m.

From m - n = 5

we have m - n + n = 5 + n

or m = 5 + n

so the answer is a)

a) m = 5+n

b) m = - 5 -

c) m = - 5+n

d) m = 5 -

2. Solve - 2 = 4r + s for s.

From - 2 = 4r + s

we have s + 4r = - 2

s + 4r - 4r = - 2 - 4r

s = - 2 - 4r

so the answer is s = - 2 - 4r

a) s = - 2 + 41

b) s = 2 - 4r

d) s = 2 + 4r
