Algebra: Solving linear equations using the distributive property Quiz
Quiz Overview
Description
This quiz assesses the skill of solving a linear equation using the distributive property, along with addition, subtraction, multiplication, and division.
Example:
Solve for x:
2(5x - 1) = 8
Solution:
2(5x - 1) = 8
(2)(5x) + (2)(-1) = 8
10x + (-2) = 8
10x - 2 = 8
10x - 2 + (2) = 8 + (2)
10x = 8 + (2)
10x = 10
(10x)/10 = (10)/10
x = 10/10
x = 1
Example:
Solve for x:
2(5x - 1) = 8
Solution:
2(5x - 1) = 8
(2)(5x) + (2)(-1) = 8
10x + (-2) = 8
10x - 2 = 8
10x - 2 + (2) = 8 + (2)
10x = 8 + (2)
10x = 10
(10x)/10 = (10)/10
x = 10/10
x = 1
