Answer:
Rs 1400
Step-by-step explanation:
Let us take the required number be x. According to question ,
=> 25% of x = Rs 350
=> 25/100 × x = Rs 350
=> x = Rs 350 × 100 / 25
=> x = Rs 1400
<h3>
• Hence the required answer is Rs 1400.</h3>
So we assume that x=x and y=y is true for both situations so
3x+2y=-2
6x-y=6
6x-y=6
add y to both sides
6x=6+y
subtract 6 from both sides
6x-6=y
subsitute (6x-6) for y in first equation
3x+2(6x-6)=-2
distribute
3x+12x-12=-2
add like terms
15x-12=-2
add 12 to both sides
15x=10
divide both sides by 15
x=2/3
subsitute
3x+2y=-2
3(2/3)+2y=-2
6/3+2y=-2
2+2y=-2
subtract 2 from both sides
2y=-4
divide both sides by 2
y=-2
x=2/3
y=-2
solution in (x,y) form
(2/3,-2)
= 0.4
because...
if you divide 6 by 3 it gives you 2.
then....
divide 2 by 5 and the answer is 0.4
