Answer:
science =
English =
Math = 4 hours
Step-by-step explanation:
let the number of hours spend on science = x
Hence the number of hours on English will be = 2x
Given that the number of hours spend on science is one third of the time spend on maths. Hence the time spend on math is 3 times that of the time spend on science. That the time spend on maths is = 3x
Hence the total time to study is
x+2x+3x
which is given as 8 hours
Hence
x+2x+3x =8
6x=8
dividing both sides by 6
Hence the number of hours foe studying science =
Number of hours to study English = =
Number of hours to study Math= =
Answer: that is -7
Step-by-step explanation:
Subtract the 2nd row from the 1st row
5x = 5
Solve for x in the equation above
x = 1
Substitute x = 1 into any of the two equations above
Let's pick the first equation; 4x + 3y = -5
4 * 1 + 3y = -5
Solve for y in the equation above
y = -3
Therefore,
<u>x = 1</u>
<u>y = -3</u>
