Answer:
sum of ratio =3+2=5
David'share=£9900x3/5=£5940
Sum of ratio for part= 4+4+2=10
for himself=£5940x4/10=£2376
for wife=£5940x4/10=£2376
for son=£5940x2/10=£1188
his wife gets over son
£2376-£1188=£1188
This is parallelogram so
8=2x
X=4
Or
3x=12
So again we will find x=4
Answer:
-9
Step-by-step explanation:
-3x+y=-7
-3x+y-2
-7-2=-9
The answer is x = 6
Explanation:
First, you must assume that 5x-10=20. Next, you add 10 to 20, which makes the equation 5x=30. Next, divide 30 by 5, which then makes the equation x=6. When you substitute 6 in the original equation, it works, because 5(6)-10 equals 20.
Answer:
(-1, 3)
Step-by-step explanation:
x - 5y = -16 [Equation 1]
-x + 3y = 10 [Equation 2]
<u>Adding both equations</u>
- x - x - 5y + 3y = -16 + 10
- -2y = -6
- y = 3
- x - 5(3) = -16
- x - 15 = -16
- x = -1
<u>Solution</u> : (-1, 3)
