How about 3x-20-2x = 26,

How about 3x-20-2x = 26,


3X-20-2X=26
First, shift it first, and move - 20 to the right. So add 20 to both sides of the formula. So we get: 3x-20-2x = 26 + 20
---〉3X-2X=46
Second: 3x-2x = 46, so, x = 46



How to calculate 3x-2 = 2x + 1


Transference
3X-2X=1+2
X=3



(3x+1)/2-2=(3x-2)/10-2x+3/5


(3x+1)/2-2=(3x-2)/10-2x+3/5
Multiply both sides by 10 to get
5(3x+1)-20=3x-2-2(2x+3)
15x+5-20=3x-2-4x-6
15x-3x+4x=-2-6+20-5
16x=7
x=7/16
