One Step Equations
Solve the One Step Equation:
x – 8 = 16
x = 24
2x + 5 = 15
x = 5
f(x) = 6x, Find f(3)
f(3) = 18
Factor the quadratic equation:
x2 + 10x + 16
(x + 2)(x + 8)
What is the first step when solving:
5x = 30
Divide both sides by 5
Solve the One Step Equation:
8x = 56
x = 7
Solve the two step equation:
3x – 8 = –5
x = 1
f(x) = 5x + 4, find f(6)
Factor the quadratic equation:
x2 – 9x + 14
(x – 2)(x + 7)
What is the first step when solving:
4x + 7 = 63
Subtract 7 from both sides
Solve the One Step Equation
x + 5 = –9
x = –14
Solve the two step equation:
x/2 + 7 = 21
x = 28
f(x) = 4x + 7, find f(–6)
Factor the quadratic equation:
5x2 + 9x + 4
(5x + 4)(x + 1)

Andrew is solving the following problem:
4x + 9 = 16
He begins by dividing both sides by 4, and then subtracts 9 from both sides. He ends with the answer
x = –5. Is he correct? Why or why not?
His is NOT correct. He did the steps in the wrong order. Subtract first, then divide. His answer should have been x = 7/4
