Here is how yah do it
The easiest approach is to multiply a number in decimal format by 100. Move the decimal: Another way to convert from decimal to percentage format is to move the decimal two places to the right.
If im correct mark brainliest
3x+2(x-1)=9x=4
We move all terms to the left:
3x+2(x-1)-(9x)=0
We add all the numbers together, and all the variables
-6x+2(x-1)=0
We multiply parentheses
-6x+2x-2=0
We add all the numbers together, and all the variables
-4x-2=0
We move all terms containing x to the left, all other terms to the right
-4x=2
x=2/-4
x=-1/2
