Four times a number minus twice another number is -16. The sum of the two numbers is -1. Find the numbers
Ivenika [448]

Answer:

2 and -3

Step-by-step explanation:

Let the numbers be x and y ∴ 4x -2y =-16......................Eqn 1

and x+y=-1.................................Eqn 2

this ⇒x=-1-y. Substitute the value of x to be=-1 -y and putting in Eqn 1 yields the following 4(-1-y)-2y =-16 0r -4-4y-2y=-16

⇒-4-6y=-16 0r =-6y=-12 ∴y is 2

⇒ and x is -3

The sum of three consecutive odd integers is 183
Tatiana [17]
Since any off integer is in the form (2x+1) then three consecutive integers who's sum is 183 will be in the form (2x+1)+(2x+3)+(2x+5)=183
6x+9=183
subtracting 9
6x=174
dividing by 2
3x=87
dividing by 3
x=29
so the integers are
2(29)+1=59
2(29)+3=61
2(29)+5=63
to check our answer let us sum up the integers
59+61+63=59+1+60+63=60+60+63=183
