Answer:

Multiply 4 to the terms inside the parentheses.

(12x+8)-2

Remove the parentheses and equate it to zero.

12x+8-2 = 0

Simplify

12x+6 = 0

Transpose 6 to the other side.

12x = -6

Divide bith sides by 12.

12x/12 = -6/12

Simplify.

x = -6/12 or -½

The sum of the number is 103.the second number is 4 times the third.the third number is 5 more then the first .what are the numb
Zigmanuir [339]

Answer:

13, 18, 72

Step-by-step explanation:

let x-5 represent the first number, since the first number is 5 less than the third number. let x represent the third number. let 4x represent the third number, since it's four times greater than the third number.

set up an equation, and make it equal to 103:

x-5+x+4x=103

solve:

6x-5=103

6x=108

x=18

so, the third number is 18.

the first number is equal to x-5, so:

18-5=13

the second number is equal to 4x, so:

4(18)=72

so, the three numbers are 13, 18, and 72.

3x-y= 17<br> -x+y= -7<br><br> Help please
AlexFokin [52]

Answer:

y = -2

x = 5

Step-by-step explanation:

3x - y = 17

-x + y = -7

here we can find the sum of the two equations

2x = 10

x = 5

now we can just plug in the value of x to find y

-(5) + y = -7

y = -2
