Multply both equations by 2 leaving
x + 2y = 8
x - 2y = -2
Add the equations giving
2x = 6
x = 3
Substitute 3 in the top equation
3 + 2y = 8
2y = -5
y = -2.5
The answer is x=6. This is because 6+4 equals 10
All you need to do is find (f+g)x = (12x) + (10(1.2)X) which = 24x
then in the multiple choice, see which one equals 24x, in this case its C.
5*1.2=6, 6x+6x = 12x*2 = 24x

Answer:
Step-by-step explanation:
x²=1.96
x²-1.96=0
(x+1.4)(x-1.4)=0
x=1.4 and -1.4
