What is liner equation with two variable?
- An equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
- For example, 10x+4y = 3 and -x+5y = 2 are linear equations in two variables.
-10x² -10y² = -300 ----a
5x² + 5y² = 150 ---- b
While trying to solve this,
We can multiply the eq. b by 2 so we will get eq. c and then add to eq. a we will get 0 as the solution.
10x² + 10y² = 300 ----c
-10x² -10y² = -300 ---a
<u>Everything cutoff, we will </u><u>get 0</u><u>, and there is no solution to these equations.</u>

$600 because you must multiply. 150/ (25/100)... 1,500/25= 600
75, because 300 (5100-4800) divided by 4 ( 2007-2011) is 75. The towns population decreased at a constant rate of 75.
Hi!
1.)
a:A u B=

(The same elements are written once.)
b:A u C

c:B u C

Note:I used dots to mean commas .
Good work!
