eq. 1 is x-2y=0
which means x=2y
eq. 2 is 4x-3y=15
subst. x=2y in eq. 2
4(2y)-3y=15
8y-3y=15
5y=15
y=3
subst. y=3 in eq. 1 we get
x=2(3)
x=6
Ans: x=6 and y=3 is the required solution.
Thank you.
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
15
(0, -12) and (-15, 0)(0, -12) and (-15, 0)(0, -12) and (-15, 0)(0, -12) and (-15, 0)
No.
-15 = 8c - 15Add 15 to each side:0 = 8cDivide each side by 8:c = 0
15 percent 0 equals 0; 0 percent 15 equals 0. Both the above are true
0 divided by15 = 0 15 divided by 0 is undetermined ( infinite)
15
y = 2x - x2y = 0Since both quantities on the right side are equal to 'y', they're equal to each other.2x - x2 = 0x (2 - x) = 0x = 0and2 - x = 0x = 2The two points of intersection are (0, 0) and (2, 0) .
it equals 4.5 :0
(0, -12) and (-15, 0)(0, -12) and (-15, 0)(0, -12) and (-15, 0)(0, -12) and (-15, 0)
No.
y=±√15
15 to the power of 0 = 1
-15 = 8c - 15Add 15 to each side:0 = 8cDivide each side by 8:c = 0
x=(-3)
(-5, 2)
