Equivalent fractions to 5/6 is 10/12 15/18 and 20/24
equivalent fractions to 2/3 is 4/6 6/9 and 8/12
Celeste is not using the correct number of apples to oranges
So use cancelation
multiply first equation by 2
2x+8y=10
times 2
4x+16y=20
now add
4x+16y=20
<u>-4x-9y=-13 +
</u>0x+7y=7
7y=7
divide by 7
y=1
subsittue
2x+8y=10
2x+8(1)=10
2x+8=10
subtract 8 from both sides
2x=2
divide by 2
x=1
x=1
y=1

Answer:
X = -1/2 or 1/2
Step-by-step explanation:
When the square root of a number is found, this usually results in 2 solutions which may be equal in size but opposite in signs.
As such,
X^2=1 to find x find the root of both sides
X = √1
X = -1 or 1
Going by this
4x^2=1
Divide both sides by 4
X^2=1 /4
taking the square root of both sides
X = √1/4
The root of 1 is -1 or 1 while that of 4 is -2 or 2 hence,
X = -1/2 or 1/2
