2/3x-1=5x

(2/3-1/5)x+=2.1
7/15x=2.1
x=4.5
Is that ok?

(3x - 1) + (2 - 5x) remove brackets

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

3x = 2.5x + 80 equation
The solution 3x = 2.5x + 80

3x=2.5X+80
3x-2.5x=80
0.5x = 80, both sides multiply by 2 at the same time
x=160

2x＋3x*80%+5x*80%=38

2X+3X*0.8+5X*0.8=38
2X+8X*0.8=38
2X*（1+4*0.8）=38
X=95/21
How do you feel wrong? Is the question OK?

The answer of 3x + 120 = 5x + 80

5x-3x=120-80
2x=40
x=20

6(3x-2)+2(5x-3)=80

6(3x - 2) + 2(5x - 3) = 80
18x - 12 + 10x - 6 = 80
18x + 10x = 80 + 12 + 6
28x = 98
x = 98 ÷ 28
x = 3.5

How to solve 2 * (5x-14) = (3x + 14)? It's better to explain it step by step

10x-28=3x+14
10x-3x=28+14
7x=42
x=42/7
x=6

5x-7=3x+8

X=7.5
5X+0=3X+8+7
5X=3X+15
5X-3X=3X+15-3X
2X=15
X=7.5

3x-[3-(5x-1)+2X]=8

3x-3+(5x-1)-2x=8
3x-3+5x-1-2x=8
6x-4=8
6x=8+4
6x=12
x=12/6
x=2
