×-y=0
×+y=-2
what is the solution to the system of equations

Use the first equation to get x in terms of y by moving y to the right side leaving you with x=y. Plug in y for x in the second equation and get y+y=-2 then 2y=-2. Divide by 2 and y=-1. Plug -1 in for y and you get x-(-1)=0 which solves to x=-1. Both variables equal -1.

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!
