Answer:
x = 0.8 y = 0.6
Step-by-step explanation:
Solve one of the equations for a single variable, I chose the 2nd equation and solved for the variable y and I got y = 2x -1.
Next plug in the value for y into the 1st equation, I got :
2x + 4 ( 2x - 1) = 4
Next solve for x by first distributing the 4 to the (2x-1), this becomes (8x -4) then add like terms and move the -4 to the other side of the equation by addition. I got 10x =8 then I divided 8/10 to solve for x and I got 0.8.
Now plug the value 0.8 in for x in the 2nd equation : 2*(0.8) - y = 1
Then solve for y by subtracting 2*(0.8) or 1.6 from 1 and I got -0.6, lastly divide by -1 to solve for y.
Answer:
It is C, in my opinion. Have a nice day. :)

P=12,500×(1+0.23)^(4)
P=28,610.83
For adding and subtracting fractions always make sure you have common denominators. Multiplication of fractions allows you to multiply fractions across without having common denominators. For mixed fractions, make sure your whole numbers are multiplied by the denominator and then added to the number in the numerator. If you have checked these steps, you should be good to go with your working and solving.
5)7/5+98/15 →LCD=15→7 14/15
6)46/9-17/6 →LCD=18 →2 5/18
7)multiply across → 4/15
8)multiply across (put a 1 under 12 if that helps) 36/4=9
9)23/4×32/3=736/12 → 61 1/3
10)LCD= 8 →1 3/8
11)(put a 1 under 9 if that helps) LCD=3→13 2/3
12)25/6+17/5 →LCD=30 →7 17/30
