Solve Multi-Step Equations
To solve an equation involving several terms, collect _________________ terms on one
side of the equation and _______________ terms on the other.
Example 1 Solve Equations by Collecting Like Terms
a) 3𝑥 + 2 = 2𝑥 − 4
b) 7 − 2𝑘 = 8 − 5𝑘
c) 5 − 3𝑚 = −2 − 2𝑚
Example 2 Solve Equations with Brackets
Expand brackets with ______________________________________________ then
collect like terms.
a) Find the root of 5(𝑦 − 3) − (𝑦 − 2) = 19
b) Solve and check. 2(𝑥 − 3) = −3(𝑥 + 5) − 6
Check:
