Solving Multi-step Equations
You are the host - a.k.a. ‘X’
In what order do people leave a party?
FAMILY….right beside you…and only you… until the end!
2x = 8
x +3 = 15
x – 5 = 20
FRIENDS….they are close to you…they stay longer than some people, but not as long as family
Because this number mingles with all other parts of the equation instead of giving most of its attention to the host (x), it is not a friend…it is an acquaintance.
ACQUAINTANCE – multiply each side of the equation by 3.
We still have company... lets continue….
Friends – add 5 to each side.
All that is left is family…a familiar one-step equation.
Family – divide each side by 2

Its easy to spot an enemy…they affect everything!
To solve, multiply each side by the reciprocal

See if you can ID the enemy, the friend, the acquaintance, a family member, the host and the door!
