Answer:
A. (4, 12)
Step-by-step explanation:
Adding the second equation to twice the first will eliminate y.
2(10x +2y) +(3x -4y) = 2(64) +(-36)
23x = 92 . . . . . . . . simplify
x = 4 . . . . . . . . . divide by 23
This value matches choice A: (4, 12).
Answer:
x = 3
Step-by-step explanation:
First you want to divide both sides by 5 to get 2x-4 = 2.
Afterwards, you add 4 to both sides of the equation. 2x = 6
Divide both sides by 2. x = 3
(7+√5)(3-√5)=21-7√5+3√5-5=16-4√5
Answer: (7+√5)(3-√5)=16-4√5
