Answer:
x = 24 + y
Step-by-step explanation:
Move all terms that don't contain x to the right side and solve.
5x − 5y = 120
y= −7x + 8
Use the second equation in the first (eliminates y)
5x − 5(−7x + 8) = 120
5x (+35x -40) = 120
40x -40 = 120
40x = 160
x = 4
----
If x = 4:
y= −7*(4) + 8
y= -28 + 8
y = -20
====
The solution is (4,-20)
Answer: x * (x + 1003)
x^2 x 3x + 1000x
x^2 + 1003x
x * (x + 1003)
An angle shaped as a long L is a right angle...
24 feet in lenght and 15 in width
Answer: Therefore it must be the first one, 40
Step-by-step explanation: Vertical angles are always congruent, which means that they are equal. x = 40
