Now David wants to solve the equation 4000x - 8000 = 16,000.
a.
What easier equation could he solve instead that would give him the same
solution? (In other words, what equivalent equation has easier numbers to
work with?)
b.
Justify that your equation in part (a) is equivalent to 4000x - 8000 = 16,000
by showing that they have the same solution.
c.
David's last equation to solve is 180 + 180 = 186 . Write and solve an
equivalent equation with easier numbers that would give him the same
answer.
