Jalil and Victoria are each asked to solve the equation ax How can Victoria justify Step 3 of her work?
- C = bx + d for x. Jalil says it is not possible to isolate x
because each x has a different unknown coefficient
Rewrite the expression on the left using the
Victoria believes there is a solution, and shows Jalil her distributive property
work
Multiply both sides by x.
ax - c = bx +
Rewrite the expression on the left using subtraction
ax-bx = d+ c
Divide both sides by x.
x(a - b) = d+
