Answer:

-5

Step-by-step explanation:

4x-3 = 7x+12

  • Subtract 12 from each side

4x-15 = 7x

  • Subtract 4x from each side

-15 = 3x

  • Divide each side by 3

-5 = x

  • Rewrite using symmetric property
<h2><u>x = -5</u></h2>

Solve the inequality<br> 3 + 9x &gt;4(x+7)<br> pls help
alexandr402 [8]

Answer:

x<5

Step-by-step explanation:

the greater sign will firstly be changed to = for better solving so we obtain

3+9x=4(x+7)by opening bracket

3+9x=4x+28

9x-4x=28-3

5x=25

divide all through by 5x

we obtain

x=5

the greater sign change here

which is x<5
