How to solve the equation of 10.8x-7.2x + 10.8

How to solve the equation of 10.8x-7.2x + 10.8


10.8x-7.2x + 10.8 = how many? Make it clear
Let 10.8x-7.2x + 10.8 = B
3.6x =b-10.8
x =b/3.6-3



Solving equations with 2x ^ 2 + 3x + 10 = 8x-1 collocation method


2x^2+3x+10=8x-1
2x^2+3x+10-8x+1=0
2x^2-5x+11=0
Δ=b^2-4ac
=25-88
=-63<0

The original equation has no solution



Solve equation 2.8x-1.6 = 4.6


2.8x-1.6=4.6
2.8x=4.6+1.6=6.2
x=6.2/2.8=62/28=31/14
