Natalija [7]3 years ago
8 0

Answer:

Let x = the 2nd number

Let x + 8 = the first number

Let 4x = the third number

x + x + 8 + 4x = 122

6x + 8 = 122

6x = 114

x = 19

x + 8 = 19 + 8 = 27

4x = 4(19) = 76

Step-by-step explanation:

The sum of three numbers is 122 . The first number is 8 more than the second. The third number is 4 times the second

Answer:

<h3>#1</h3>

<u>The system of equations:</u>

  • 2x + 7y = -11
  • 3x + 5y = -22

Solve by elimination.

<u>Triple the first equation, double the second one, subtract the second from the first and solve for y:</u>

  • 3(2x + 7y) - 2(3x + 5y) = 3(-11) - 2(-22)
  • 6x + 21y - 6x - 10y = -33 + 44
  • 11y = 11
  • y = 1

<u>Find x:</u>

  • 2x + 7*1 = -11
  • 2x = -11 - 7
  • 2x = -18
  • x = -9

<u>The solution is:</u>

  • x = -9, y = 1
<h3>#2</h3>

<u>Simplifying in steps:</u>

  • 8u - 29 > -3(3 - 4u)
  • 8u - 29 > - 9 + 12u
  • 12u - 8u < -29 + 9
  • 4u < -20
  • u < -5
