The solutions for the following system of equations will be (–1, 6) and (1, 6). Then the correct option is B.
The equations are given below.
–3x² + 4y = 21 ...1
4x² + y = 10 ...2
Multiply equation 1 by 4 and equation 2 by 3, then we have
–12x² + 16y = 84
12x² + 3y = 30
Add both equations, then we have
19y = 114
y = 6
From equation 2, we have
4x² + 6 = 10
4x² = 4
x² = 1
x = ±1
x = 1, –1
Then the correct option is B.
