Solve the system using elimination and describe your steps. be sure to verify your solution. • x = y - 3 2x + y = 12

So these are our two equations:

Before we can use elimination, subtract y on both sides of the first equation:

Now we are able to use elimination. To eliminate the y variable, add the two equations together to get . From here we can solve for x.

For this, just divide both sides by 3 and your first answer will be

Now that we have the value of x, substitute it into either equation to solve for y:

In short, x = 3 and y = 6.

it is x equals 3   plese mark me really need it

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!
