Answer:
5x - y = 10x + 3y = 4
5x - y = 4..... 1
10x + 3y = 4.....2
multiply by -2 in eq 1 in both sides
-10x + 2y = -8
10x +3y = 4
eliminate one variable by adding the equations
5y = -4
y = - 4/5
sub the value of y in..1
5x - y = 4
5x + 4/5 = 4
5x = 16/5
divide by 5 on both sides
x = 16/25
(x ; y)
(16/25 ; -4/5)
The slope of diagonal <em>AB</em> is 0 and its equation is y=2.
Answer:
You would end up at (9,6)
X/3=2
x=6
x/5=3
x=15
x/7=2
x=14
Each time, you multiply both sides by the denominator.
Hope this helps :)
