The solution to the system of equations is (x, y) = (2, -1).
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
WE are given the system of equations
2x−y=5
y = 2x - 5
y=3x−7
Adding the two equations Then divide by 2
Subtracting the second equation from the first gives;
0 = x -2
x = 2
y = -1
therefore, The solution is (x, y) = (2, -1).
The solution to the system of equations is (x, y) = (2, -1).

Answer:
.80x
Step-by-step explanation:
If the price is reduced by 20% we are paying 100-20 or 80 percent
The new price is
x* 80%
.80x
Step-by-step explanation:
step 1. The circumference (c) of a circle is the diameter of a circle x pi. c = d(pi) = 14pi.
step 2. The area (A) of a circle is the radius of a circle squared x pi. The radius of a circle is 1/2 x the diameter. A = (14/2)^2(pi) = 49pi.
Answer:
Step-by-step explanation:
<u>The interior and exterior angles are supplementary:</u>
- A + 108° = 180°
- A = 180° - 108°
- A = 72°
