Answer:
No solution
Step-by-step explanation:
Because BDC is 20, and DC = DB, DBC is also 20 degrees. ABD would then be 160 since DBC and ABD has to equal 180. You know ADB is 35 so 160 + 25 + x has to equal 180. But 160 + 25 is already 185, and x can't be negative, so no solution.
The value of x in the rectangle is 3
The value of RN and TE are 20 units and 20 units
<h3>How to find sides of a rectangle?</h3>
The diagonal bisect each other in a rectangle.
Therefore,
2x + 4 = 3x + 1
2x - 3x = 1 - 4
-x = - 3
x = 3
Therefore,
TE = 2(3x + 1) = 2(10) = 20 units
RN = 2(2x + 4) = 2(10) = 20 units

Answer:
y variable will be elimited when adding the system of equations
x = 2 or y = 3
Step-by-step explanation:
- x + 6y = 16
8x - 6y = -2
Add both equations
(-x + 8x) + {6y + (-6y)} = 16 + (-2)
7x + 6y - 6y = 16 - 2
7x + 0 = 14
7x = 14
x = 14/7
x = 2
- x + 6y = 16
- 2 + 6y = 16
6y = 16 + 2
6y = 18
y = 18/6
y = 3
the x variable will be eliminating when adding the system of equations and the
y variable will be elimited when adding the system of equations
or the sum of the system equations is negative 8X = 14 or
x = 2 or y = 3
or there's only one solution to the system equations
