I'm assuming the fraction is 12/36 which would equal 3.33 as a decimal
Either use a graphing calculator or substitute the value of x for x
Answer: x=-2/5
Step-by-step explanation:
1. Expand: 3x+6=4-2x
2. Subtract 4 from both sides: 3x+6-4=-2x
3. Simplify 3x+6-4 to 3x+2: 3x+2=-2x
4. Subtract 3x from both sides: 2=-2x-3x
5. Simplify -2x-3x to -5x: 2=-5x
6. Divide both sides by -5: -2/5=x
7. Switch sides: x=-2/5
