Answer:
The Percent change is -30% (decrease)
In this case we have a negative change (decrease) of -30 percent because the new value is smaller than the old value.
Step-by-step explanation:
Here, To find the percentage change, use this formula
<h3>
<u>Formula</u>:</h3>
Percent change = New - Old ÷ |Old| × 100%
Percent change = 210 - 300 ÷ |300| × 100%
Percent change = -90/300 × 100%
Percent change = -30% (decrease)
Thus, The Percent change is -30% (decrease)

2x + y = 5
x − 2y = 10
y = 5 − 2x
x − 2(5 − 2x) = 10
x − 10 + 4x = 10
5x − 10 = 10
<em>add 10 to each side</em>
<em>5x-10+10 = 10 + 10</em>
<em>5x=20</em>
5x = 0 <em>this is the error</em>
He needs to add 10 to each side
