<h3>Answer:</h3>
x=5, y=2
<h3>Explanation:</h3>
The second equation gives an expression for x that can be substituted into the first equation.
... (y+3) +y = 7 . . . . . .substitute y+3 for x
... 2y + 3 = 7 . . . . . . . colect terms
... 2y = 4 . . . . . . . . . . subtract 3 from both sides
... y = 2 . . . . . . . . . . . . divide both sides by 2
Using the expression for x, we can find its value.
... x = y + 3
... x = 2 + 3 . . . . . . . . . substitute for y
... x = 5
The solution is (x, y) = (5, 2).
a straight line is 180° so:
x+2/3x=180
multiply everything with 3 so that you'll looser the denominator:
3x+2x=540
5x=540
x=540:5
x=108
(2/3x= 72)
X equals negative b, plus or minus the square root of, b squared minus four a c all divided by two a
