How to solve 2 * 3x + 3 * 2x = 108 The number of men and women in a class is 3:2, 2 pencils for each boy and 3 pencils for each girl, a total of 108. How many people are there in the class

How to solve 2 * 3x + 3 * 2x = 108 The number of men and women in a class is 3:2, 2 pencils for each boy and 3 pencils for each girl, a total of 108. How many people are there in the class

There are 45 students in the class
Suppose x men, then 2x women
2X + 3 molecule 2x * 3 = 108
2x+2x=108
4x=108
x=27
There are 27 males and 18 females
18+27=45

Solve the equation 2x * 3-3x * 2 + 1 = 0

2x*3-2x*2-x*2+1=0
2x*2(x-1)-(x*2-1)=0
(2x*2-x-1)(x-1)=0
X = - 1 / 2 or x = 1

How to solve 2x-1 = 3x-3

2X－3X＝3＋1
－X＝4
X＝－4
