Answer:
x + y = 4 Equation 1
y = 2x -1 Equation 2
-2x + y = -1
x + y = 4
Subtract
You will get
- 3x = -5
Divide by -3
-3x / -3 = - 5 /-3
x = 5/3
Substitute x into equation 1
x + y = 4
x = 5/3
5/3 + y = 4
y = 4 - 5/3
y = 7/3
x = 5/3 y = 7/3
Hope this helps.

Answer:
A. c (in $) = 110(8) +175
Step-by-step explanation:
$175 is the starting price so in terms of an equation or an equation of a line it is the "b" or y-intercept.
c is the "y" or the depedent variable to solve for.
$110 is the increasing interval that is multiplied by the known variable, "x".
8 is the second variable, "x" but is known.
