Question

1.

Answer 1

Answer:

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
