Question

1) a - c = d - r , solve for A.

2) u = ak/b , solve for A.
3) am = n + p , solve for A. Literal equations! Show solution please! Thank you in advance!

Answer 1

1) a - c = d - r --> Add c to both sides
a = c + d - r

2)u = ak/b -->Times both sides by b
ub = ak --> Divide both sides by k
a = ub/k

3)am = n + p --> Divide both sides by m
a = n + p / m
