Answer:

Step-by-step explanation: multiply 2 with 3x-1

6x-2

multiply 9 with x-2

9x-18

form equation:

2(3x-1)=9(x-2)-7

or, 6x-2=9x-18-7

or, 9x-18-7=6x-2

or, 9x-6x= -2+18+7

or, 3x=23

or, x=23/3

Ans:  x= 7.67

Multiply 2*3x and 2*-1 for the left side. On the right side multiply 9*x and 9*-2.
6x - 2 = 9x - 18 - 7.
Combine like terms. 6x - 2 = 9x - 25.
Then add 2 and subtract 9x.
-3x = -23.
Divide the negative
3x = 23. Then divide 3
x = 23/3 = 7.667...
