yes how you doing tonight
Answer:
y = 4
x = -1
Step-by-step explanation:
4x + 2y = 4 Eq. 1
3x - y = -7 Eq. 2
from the Eq. 2
3x = y - 7
3x + 7 = y Eq. 3
Replacing the value of the Eq. 3 in the Eq. 1
4x + 2(3x+7) = 4
4x + (2*3x + 2*7) = 4
4x + (6x + 14) = 4
10x + 14 = 4
10x = 4 - 14
10x = - 10
x = -10/10
x = -1
from the Eq. 3
3x + 7 = y
3*-1 + 7 = y
-3 + 7 = y
4 = y
Check:
from the Eq. 1
4x + 2y = 4
4*-1 + 2*4 = 4
-4 + 8 = 4
The equation with 15 will be y = 15x.
<h3>What is an equation?</h3>
The equation is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line. The equation of a line in a general form can be written as below:-
y = mx + c
Where m is the slope and c is the y-intercept. The equation for the constant of proportionality 15 can be written as below:-
y = 15x
Here, y and x are variables and 15 is the constant value and is defined as the slope of the line.
Therefore, the equation with 15 will be y = 15x.

X is unknown
Quarters 25x
Dimes 10(x+5)
Nickes 5 (x-4)
Solve for x first
25x + 10(x+5) + 5(x-4) = 470
40x + 50 - 20 = 470
40x = 440
x = 11, number of quarters
