1. X + 7 x + 2 = 1 / 2, 2.5 4x-6 = 2x + 1 / 3

1. X + 7 x + 2 = 1 / 2, 2.5 4x-6 = 2x + 1 / 3


1. Multiply both sides by 2 (x + 7)
2x+4=x+7
2x-x=7-4
∴x=3
Test: x = 3 is the solution of the equation
The solution of the equation is x = 3
2. Multiply both sides by 15
12x-18=10x+5
12x-10x=5+18
2x=23
∴x=23/2



X + 2 / 3-x = 1 / 2 + X + 1 / 3
How to solve this equation? The result is x = - one third, but I don't know how to solve it. Can we give a process?


X + 2 / 3-x = 1 / 2 + X + 1 / 3
Multiply both sides by 2 (x + 3) to get
2(2-x)=(x+3)+2
4-2x=x+5
3x=-1
X = - 1 / 3



2X - one third (x + 1) = 4x - (2x plus one half)


Hello: 2x - one-third (x + 1) = 4x - (2x plus one-half) 2x-1 / 3x-1 / 3 = 4x-2x-1 / 25 / 3x-1 / 3 = 2x-1 / 25 / 3x-2x = 1 / 3-1 / 2-1 / 3x = - 1 / 6x = 1 / 2. If you don't understand this question, please follow it up. If you are satisfied, please send another question or click to me for help
