-2y + 2
Explanation
We have (x - y + 1) - (x + y - 1)
Let’s expand the Parentheses
= x - y + 1 - x - y + 1
Then let’s group the like terms
= (x - x) + (- y - y) + (1 + 1)
= 0 - 2y + 2
= 2y + 2

The value of x to the nearest whole number is 68 degrees
<h3>Equations and expressions</h3>
Given the trigonometry function shown below:
y = 50 tan x
For the coordinate (x, 125)
If the value of y is 125, then;
125 = 50tanx
tanx = 125/50
tanx = 2.5
x = arctan(2.5)
x = 68.19
Hence the value of x to the nearest whole number is 68 degrees

Answer:
x = -1.25
Step-by-step explanation:
2.25x + 5 = 13.5x + 14
subtract five from both sides
2.25x = 13.5x + 9
subtract 13.5x from both sides
-11.25x = 9
swap the negative
11.25x = -9
divide 11.25 from both sides
x = -1.25
