I know none of these are actually the answer but odysseyware gave me credit for

Answer:
Step-by-step explanation:
x + y = 25 ...........................(1)
{4x + 2y =64} / 2 divide the equation by 2
2x + y = 32 ........................(3)
Step Two
subtract (1) from (3)
2x + y = 32
x + y = 25
x = 7
Therefore from equation 1 we get x + y = 25
but x = 7
7 + y = 25 Subtract 7 from both sides.
y = 25 - 7
y = 18
Check
4*x + 2*y = 64
4*7 + 2*18 =? 64
28 + 36 = ? 64
64 = 64
The checks out to be the right answer.
Answer:
y =
x + 8
Step-by-step explanation:
- Find the slope:
( parellel lines have the same slope)
- Create an equation using the given ordered pair to find the
y-intersept (b): 10 =
(6) + b
- Reduce the numbers with the greatest common factor 3 : 10 = 2 + b
- Move the variable to the left-hand side and change its sign : -b + 10 = 2
- Calculate the diffrence : -x = -8
- Change the signs on both sides of the equation: x = 8
Use the slope and y-itersept to creat the equation : y =
x + 8
