Answer:
31.5
Step-by-step explanation:
Ok.
2/3x - 9 = 12
2/3x = 21
x = 21*(3/2)
x = 63/2 = 31.5
Answer:
[tex]x=\frac{63}{2}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} \times x-9=12[/tex]
Add 9 to both sides:
[tex]\frac{2}{3}x-9+9=12+9\\\frac{2}{3}x=21[/tex]
Multiply both sides by 3/2:
[tex](\frac{3}{2} )\times(\frac{2}{3}x)=(\frac{3}{2} )*(21)\\x=\frac{63}{2}[/tex]
x = 63/2 is your answer.
