X+2y = 9 ---------eq.1
x-y =6 ----------- eq.2
x = 9 -2y (from eq. 1)
Now substitute the value of x in the second eq.2
9-2y-y =6
-3y = -3
y =1
So,
x +2 (1)= 9
x= 7
Answer:
Step-by-step explanation:
192 divided by 2 = 96 times 3 =288
The answer is f(x)=4x^2+8x-12
The answer is 4. (8-3)2=10, because 8-3 is 5 and 5 multiplied by 2 is 10. (5-2)2=6, because 5-2 is 3 and 3 multiplied by 2 is 6. that leaves us with 10-6, which equals 4
