( 2 , 4 )
Step-by-step explanation:
Given:
...............Equation ( 1 )
................Equation ( 2 )
To Find:
x = ?
y = ?
Solution:
Substitute Equation ( 1 ) in Equation ( 2 ) we get

Now Substituting x = 2 in Equation ( 1 ) we get

Therefore the Final Solution is
x = 2 and y = 4
( 2 , 4 )
Answer:
3.125 was Jeter's batting average
Step-by-Step Explanation:
Just divide his bat number with the total hits
So, ---> 500 at bats / 160 hits
500/160 = 3.125
X = pencils, y = pens
8x + 6y = 8.50
4x + 4y = 5.....multiply by -2
----------------
8x + 6y = 8.50
-8x - 8y = -10 (result of multiplying by -2)
-----------------add
-2y = - 1.50
y = -1.50 / -2
y = 0.75 <=== pens cost 0.75
4x + 4y = 5
4x + 4(0.75) = 5
4x + 3 = 5
4x = 5 - 3
4x = 2
x = 2/4
x = 0.50 <== pencils cost 0.50
