Okay so for substitution, chose one of of the equations to solve for x. Let's solve for the second one. So you have 2x-8y=32.
Start by adding 8y to both sides:
2x=8y+32.
Then you have to get x by itself so you divide both sides by 2 which will give you:
x=4y+16.
Now you have:
6x-4y=36
x=4y+16 (this was 2x-8y=32)
Now, plug in the second equation to the first one. You would do so by plugging in the second equation to where you see x. You would have:
6(4y+16)-4y=36
Now, multiply the 6 with the 4y and 16. you would then have:
24y+96-4y=36.
Now, combine your like terms to get:
20y+96=36
Then subtract 96 to both sides:
20y=-60
Then divide both sides so that you have y all by itself:
y=-30!
You now have the answer for y, so now plug what you got for y into the other equation: x+4y=16:
x+4(-30)=60
Solve for x:
x-120=60
add 120 to both sides:
x=180!
so Your answer is Y=-30 and X=180
I hope this helped:)
Answer:
65 and 67
Step-by-step explanation:
two consecutive odd numbers would look like this:
x and x + 2
this is because of how counting numbers works:
1 2 3 4 5 6 7
the consecutive numbers here would be 1, 3, 5, 7, etc.
if one number (x) was 1, the next number would be (x + 2) which is three. This formula will work for all consecutive odd numbers.
so, x + x + 2 = 132
2x + 2 = 132
-2 -2
2x = 130
/2 /2
x = 65
the first number is x = 65
the second number is x + 2 which means this number is 65 + 2 = 67
(check: 65 + 67 = 132)
