2. A two-step equation worked out
Two – Step Equations
How are they solved?
What do they look like?
You isolate the variable to one side of the equation.
You must remove both numbers and both operation that are connected to the variable.
Use the inverse operations.
Remove add/subtract first, then multiplication / division next.
4x – 5 = 19
(Y ÷ 3) + 2 = 6
A two-step equation worked out
4x – 5 = 19
+5 = +5
4x = 24
4x ÷ 4 = 24 ÷ 4
X = 6
4x – 5 = 19
Remove add/subtract
4x = 24
Remove mult. / division
x = 6
(y÷3) + 2 = 6
-2 = -2
y ÷ 3 = 4
y ÷ 3 x 3 = 4 x 3
y = 12

3. Practice Explain the first step to solve this equation: 5x – 10 = 25
Explain the second step to solve this equation:
Y + 12 = 20 4

4. Practice
Solve:
Y - 9 = 1 6
Solve:
5 + 7x = 54

5. Practice Identify the Error: Y + 11 = 17 7 7 ∙ y + 11 = 17 ∙ 7
- 11 = -11
y = 108
Identify the Error:
8x – 16 = 72
- 16 = 16
8x = 56
x = 7
