The equation 1.2 (3b - 1) + 2.2 - 1.8b = 0 solved for the variable b is -5/9
How to solve the equation for the variable b
From the question, we have the following parameters that can be used in our computation:
1.2 (3b - 1) + 2.2 - 1.8b = 0
Open the brackets
So, we have the following
3.6b - 1.2 + 2.2 - 1.8b = 0
Collect the like terms
This gives
3.6b - 1.8b = 1.2 - 2.2
When the like terms are evaluated, we have
1.8b = -1
Divide both sides by 1.8
b = -1/1.8
So, we have
b = -5/9
Hence, the equation solved for the variable b is -5/9
