Add 10 to both sides.
What is the first step in solving 4𝑥 + 6 = 22?
Look at where the variable is positioned.
True or False: The equation 7𝑥 = 21 has one solution.
Consider the values of x we can obtain.
If 2(𝑥 - 3) + 4 = 10, what is the solution for 𝑥?
Distribute and simplify, then isolate x.
Solve for 𝑥 in the equation 4 - 3(2𝑥 + 1) = 8.
