Answer:
1. y = 1/7 = 0.143
2. y = 2/3 = 0.667
Step-by-step explanation:
STEP 1
:
Equation at the end of step 1
(3y - 2) • (7y - 1) = 0
STEP 2
:
Theory - Roots of a product
2.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
2.2 Solve : 3y-2 = 0
Add 2 to both sides of the equation :
3y = 2
Divide both sides of the equation by 3:
y = 2/3 = 0.667
Solving a Single Variable Equation:
2.3 Solve : 7y-1 = 0
Add 1 to both sides of the equation :
7y = 1
Divide both sides of the equation by 7:
y = 1/7 = 0.143
