The answer choice which represents a solution to the system of equations is; (–2, 10).
Which answer choice is a solution to the systems of equations?
The system of equations as given in the task content is;
-6x - (2/5)y = 8
(1/2)x +3y = 29
Hence, by making x subject in equation 1 and substitution; we have;
x = (-0.4y -8)/6
Hence; (0.4y -8)/12 + 3y = 29.
(0.4y -8) + 36y = 348
35.6y = 356
y = 10
and x = (-0.4(10) -8)/6 = -2.
