Answer:
(2/3, 17/3)
Step-by-step explanation:
put x and y coordinates value in given equation to check equality. it equality holds that's the coordinates we are looking for.
here 2nd coordinate holds the equality
Answer:
x = 5
y = 4
Step-by-step explanation:
1. 2x + 2y = 18
2. x + 3y = 17
Multiply the first equation by 1 and the second equation by 2 to eliminate x
We have
2x + 2y = 18
2x + 6y = 34
Subtract equation 2 from equation 1
-4y = -16
Divide both sides by -4 to isolate y
-4y/-4 = -16/-4
y = 4
Now substitute 4 for y in either equation to get x. Using equation 2 we have
x + 3y = 17
x + 3 x 4 = 17
x + 12 = 17
Subtract 12 from both sides
x + 12 - 12 = 17 - 12
x = 5
x = 5 and
y = 4
4500 is both divisible by 5 and 9
4500/9=500
4500/5=900
Cool the answer is y because she spend that
