Hello.

In order to solve this equation, we need to isolate the variable (in this case, the variable is x)

The first step is to use the Distributive Property and distribute 3:

\mathrm{3(x-1)=2x+9}

\mathrm{3x-3=2x+9}

Now, add 3 to both sides:

\mathrm{3x-3+3=2x+9+3}

\mathrm{3x=2x+9+3}

\mathrm{3x=2x+12}

Now, subtract 2x from both sides:

\mathrm{3x-2x=2x-2x+12}\\\mathrm{3x-2x=12}

\mathrm{x=12}

Therefore, the answer is

\mathrm{x=12}

I hope it helps.

Have a nice day.

Please tell me how do you simplify the expression???? <br> x^15 · y^9<br> over<br> x^8 · y^3
anyanavicka [17]

Answer:

x^7 * y^6

Step-by-step explanation:

In the equation: \frac{x^{15} * y^9 }{x^8 * y^3}

x's can be simplified and y's can be simplified!

Always remember that for exponents, you subtract the powers when dividing

so for x: 15-8 = 7

for y: 9-3 = 6

so the final answer is: x^7 * y^6
