Answer:
(x, y) = (-2, -1) or (2, 1)
Step-by-step explanation:
Substitute for x in the first equation:
(2y)^2 +3(2y)y = 10
10y^2 = 10
y^2 = 1
y = ±1
x = 2y = ±2
Solutions are (x, y) = (-2, -1) or (2, 1).
The solution of an equation is the true value of the equation.
The true statement is <em>(a) Dr. Ellison is right</em>
<em />
The equation is given as:
The solution is given as: (1,18)
Substitute 1 for x and 18 for y.
So, we have:
Multiply
Add
The above equation is true.
Hence, the true statement is (a) Dr. Ellison is right
