<span>3x+5y=4...(1)
2x-y=-7...(2)
by(2) : y = 2x+7
subsct in (1) :
3x +5(2x+7) = 4
13x = - 31
x = -31/13
y = 2(-31/13)+7 = 29/13</span>
Number 2. x=5/3 and y=5
number 4. x=7/3 and y=-5
that's all i could answer. and for number 1 x=-3
<span>here the Answer: -3a-4b+8c.

The system of linear equations that may be used in order to solve this problem is as follows:
x + y = 37
2x + 3y = 95
This is considering that x is the number of bracelets sold and y is the number of necklaces.
The values of x and y in the equation are 16 and 31, respectively.
Thus, the answer is 16 bracelets and 21 necklaces.
Answer:
A. Height is input, Weight is output
Step-by-step explanation:
We are given the statement,
"Weight is a function of height".
As we know,
<em>In a function of the form 
, the input variable is 'x' and the output variable is 'y'.</em>
If we write the given statement in the form , we get,
This means that the input variable is 'Height' and the output variable is 'Weight'.
Hence, option A is correct.
