Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
Answer:
Yes
Step-by-step explanation:
Question <span>2x+3y=48
Answer </span><span>x = 24 + -1.5y
Question </span><span>x+6y=11
</span>Answer x = 11 + -6y
The equation is
5x - 13 = 3x + 21
when solved, we get
x = 17
Two and Nine are the pair of the numbers
