Solution for 1/5(5x+12)=18 equation:
<span>x in (-oo:+oo)
(1/5)*(5*x+12) = 18 // - 18
(1/5)*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
1/5*(5*x+12)-18 = 0
x-78/5 = 0
x-78/5 = 0
x-78/5 = 0 // + 78/5
x = 78/5
x = 78/5

Answer:
- x < 2.5
- x > 2.5
Step-by-step explanation:
One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.
<h3>1.</h3>
For x=0, you have ...
5 > -5 . . . . . true; the solution space is x < 2.5
__
<h3>2.</h3>
For x=0, you have ...
-25 > -5(2.5)
-25 > -12.5 . . . . . false; the solution space is x > 2.5
_____
<em>Alternate solution</em>
<h3>1.</h3>
Subtract 5:
-4x > -10
Divide by -4
x < 2.5
__
<h3>2.</h3>
Divide by -5:
5 < x +2.5
Subtract 2.5
2.5 < x
x > 2.5
