ONE question with picture included! no need to do part c :)

x + y = 24

16x + 20y = 434

x = 11.5

y = 12.5

Step-by-step explanation:

Part A:

x + y = 24

16x + 20y = 434

Part B:

simplify the second equation to find a "kind of answer" to a variable,

so we could simplify it to either y = 21.7 - 0.8x or x = 27.125 - 1.25y

in this case we will use y = 21.7 - 0.8x

substitute your new value of y into the first equation:

x + (21.7 - 0.8x) = 24

now, we can solve this to find the actual value of x: x = 11.5

so plug in your real x value to the simplified second equation (y = 21.7 - 0.8x)

you get y = 12.5
