Answer:
(8,4)
Step-by-step explanation:
y and -y cancels out leaving you with "12x=96"
that simplifies to "x=8"
Then you substitute 8 into the "x" from either equation and y should equal 4
Add 9 to the equation to get rid of -9 of the left side. Then you have n/4 = 2. Multiply the equation by 4 to get rid of the 4 on the left side in the denominator. You would have n = 8 which is your final answer!. If this is right could I possibly have brainliest? Hope this helped!! :)
√x+5 -1 = 0
Solve for X:
Add 1 to each side:
√x+5 = 1
Remove the radical by squaring both sides:
(√x+5)^2 = 1^2
Simplify:
x+5 = 1
Subtract 4 from each side:
x = -4
The answer is C.
