If 3 squared is 9 then 9 times -2 is -18 plus 7 is -11
Answer: It's C.
Step-by-step explanation:
The solution of the given equation is (3,6). The correct option is B.(3,6)
<h3>Given equations,</h3>
![y=x+3.......(1)\\4x+y=18.....(2)](https://tex.z-dn.net/?f=y%3Dx%2B3.......%281%29%5C%5C4x%2By%3D18.....%282%29)
<h3>How to solve the equations?</h3>
putting the value of y from equation (1) in equation (2) , we get
![4x+x+3=18\\](https://tex.z-dn.net/?f=4x%2Bx%2B3%3D18%5C%5C)
![5x=18-3\\5x=15\\x=3](https://tex.z-dn.net/?f=5x%3D18-3%5C%5C5x%3D15%5C%5Cx%3D3)
substitute the value of x=3 in equation (1) we get,
![y=3+3\\y=6](https://tex.z-dn.net/?f=y%3D3%2B3%5C%5Cy%3D6)
Hence, the solution of given equation is (3,6).
So, the correct option is B.
