3.22 x 104 = 334.88
(Hope this helps ;3)
3x + 7 <_ 4x -8
Subtract 3x from both sides.
3x - 3x = 0x
4x - 3x = 1x (or just x)
7 <_ x -8
Add 8 to both sides.
7 + 8 = 15
-8 + 8 = 0
x _> 15 is the solution for the first inequality.
Although A.) is the only one with x_>15, let's continue to ensure our answer.
-2x + 3 _> 1
Subtract 3 from both sides.
3 - 3 = 0
1 - 3 = -2
-2x _> -2
Divide both sides by -2 to solve for x.
-2x / -2 = x
-2 / -2 = 1
Remember to flip the inequality when dividing or multiplying by a negative.
x <_ 1 is our other inequality.
Our answers are:
x_> 15 and x<_1
