Question

Solve for the variable c in this equation:

a(c + b) = d

Answer 1

c=d/a−b

Answer 2

You first divide each sidde by a
c+b = d/a

Answer 3

You then subtract b from both sides

c= (d/a) -b

Answer 4

Jpenrod's answer is actually incorrect because the -b is on the top, not the bottom.

Answer 5

In this sort of problem, "solving" means "isolating." In other words, you want an equation for c in terms of a, b and d.

In a(c + b) = d, we can simplify the work involved by dividing both sides of this equation by a:

c + b = d/a

Now, to isolate c, subtract b from both sides of the equation:

c = (d/a) - b

It's always wise to use parentheses to eliminate any ambiguity regarding what is meant.

Answer 6

can someone draw it out? sorry I'm slow but this is how I learn. :) thanx
