Please help! I really need it!

Answer 1

Answer:

1.  x > 4

2.  m < 2

3.  x > 2

4.  x < -6

Step-by-step explanation:

These 4 inequalities will be solved the same way we solve equations. We take variables to one side and numbers to another and use algebra to solve. Each of them are solved shown below:

1.

$4+6x$

so x is greater than 4, we can write (variable first):

x > 4

2.

$m+16>8m+2\\16-2>8m-m\\14>7m\\\frac{14}{7}>m\\2>m$

so m is less than 2, we can write:

m < 2

3.

$5x-1>13-2x\\5x+2x>13+1\\7x>14\\x>\frac{14}{7}\\x>2$

so x is greater than 2, we can write:

x > 2

4.

$-3x-2>-x+10\\-2-10>-x+3x\\-12>2x\\\frac{-12}{2}>x\\-6>x$

so x is less than -6, we can write:

x < -6
