Linear Equations Answer Key
📚 Part 1: Multiple Choice Answers
✏️ Part 2: Open-Ended Solutions
Answer: x = -0.5
Solution:
4x + 6 = 4
4x + 6 - 6 = 4 - 6
4x = -2
4x ÷ 4 = -2 ÷ 4
x = -0.5
Answer: y = 1.5
Solution:
6y - 4 = 5
6y - 4 + 4 = 5 + 4
6y = 9
6y ÷ 6 = 9 ÷ 6
y = 1.5
Answer: f = -3.6
Solution:
2.5f + 1 = -8
2.5f + 1 - 1 = -8 - 1
2.5f = -9
2.5f ÷ 2.5 = -9 ÷ 2.5
f = -3.6
Answer: a = -10
Solution:
-3a + 5 = 35
-3a + 5 - 5 = 35 - 5
-3a = 30
-3a ÷ (-3) = 30 ÷ (-3)
a = -10
Answer: b = -2
Solution:
7b + 12 = -2
7b + 12 - 12 = -2 - 12
7b = -14
7b ÷ 7 = -14 ÷ 7
b = -2
