Answer:
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

Answer:
x = 3 and 1/3, or 3.333333...
Step-by-step explanation:
I'm assuming again that you want to find x
–4 + 3 ( 2 – x) = –8
Multiply
-4 + 6 - 3x = -8
Add 4 to both sides
6 - 3x = -4
Subtract 6 from both sides
-3x = -10
Multiply by -1
3x = 10
Divide by 3
x = 10/3
