dejt4u:Thanks a lot, am writing them out immediately. what method did you use from 1-3? |
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Sirgay: 9:14pm On Nov 26, 2017 |
please check solution 1, you multiple equation 3 by 2, but it didn't effect on 2x dejt4u |

Sirgay: X + Y/2 = 1 --- EQN1 X/2 + Y/3 = 17/6 --- EQN2 MAKE X IN EQN1 THE SUBJECT OF THE FORMULA X = 1 - Y/2 --- EQN3 PUT EQN3 IN THE X IN EQN1 1/2((2 + Y)/2) + Y/3 = 17/6 (6 + 3Y + 4Y)/12 = 17/6 36 + 18Y + 24Y = 204 Y = 4 SUBTITUTE Y = 4 FOR Y IN EQN 1 X - 4/2 = 1 X = 3 |

dejt4u: Recheck your solution on question 4,bro When a fraction is dividing a whole number, you have to take the reciprocal of the fraction into cognizance. 240/23 /6= 23/240*6 =23/40 for b....... |

Problem: Solvex−y2=1;x2+y3=176 Steps: I will solve your system by substitution. (You can also solve this system by elimination.) x+−12y=1;12x+13y=176 Step: Solvex+−12y=1for x: x+−12y+12y=1+12y(Add 1/2y to both sides) x=12y+1 Step: Substitute12y+1forxin12x+13y=176: 12x+13y=176 12(12y+1)+13y=176 712y+12=176(Simplify both sides of the equation) 712y+12+−12=176+−12(Add (-1)/2 to both sides) 712y=73 712y712=73712(Divide both sides by 7/12) y=4 Step: Substitute4foryinx=12y+1: x=12y+1 x=12(4)+1 x=3(Simplify both sides of the equation) Answer: x=3 and y=4 Life don easy sha, I swear . Just a simple search on google for d question 1 |

x-y/2=1, x/2+y/3=2 5/6.
2x-y=2, 3x+2y=17.
2x-y=2 multiply by 3, 3x+2y=17 multitply by 2.
U will get, 6x-3y=6, 6x+4y=34.Then by elimination method,
6x-3y=6
-
6x+4y=34. U will get,-7y=-28,then,y=4.
for x: 2x-4=2, which means 2x=2+4, so 2x=6, so x=3. |

pls help me here I'm stuck A utility company has a small power plant that can produce a kilowatt hours of electricity daily at a cost of 10 - x/10^5 cents each for 0 < x < 8 x 10^5. Consumers will use 10^5(10 - p/2) kilowatt hours of electricity daily at a price of p cents per kilowatt hour. What price should the utility charge to maximize its profit? |
