Solve for the indicated variable in each literal equation 2p+5r=q for px/5-g=a for x a/b=c for b

a) 2p+5r=q

b) x/5-g=a

c) a/b=c

An expression for ...

a) p

b) x

c) b

In general, you "undo" what was done to the variable. You do that in the reverse of the order in which it was done.

a) The variable is multiplied by 2 and 5r is added. We add the opposite of 5r and multiply by the reciprocal of 2.

b) The variable is multiplied by 1/5 and g is subtracted. We add g and multiply by 5.

c) The reciprocal of b is computed, then multiplied by a. We divide by a, then take the reciprocal.
