Answer: x> 1/2
Step-by-step explanation:
if 2x+1∠ 8x-2
inequality , treat this problem like any other equation
have the unknown(x) in one side, and the values on the other side
2x-8x < -1-2
-6x< -3 we multiply by -1, do not forget if we multiply by -1 the sign will change
6x>3 divide by 3
2x>1
x>1/2
The only error you made is on problem 3. Everything else is correct. Nice work.
-------------------------------------------------------
Here is how to solve problem 3
Plug x = 1 into the equation and solve for y
-3x + y = 1
-3*1 + y = 1 ... replace x with 1
-3 + y = 1
y - 3 = 1
y - 3 + 3 = 1 + 3 .... add 3 to both sides
y = 4
<h3>The answer is 4</h3>
-------------------------------------------------------
Verifying the answer:
Plug (x,y) = (1,4) into the equation. Both sides should be the same number after simplifying both sides.
-3x + y = 1
-3*1 + 4 = 1 ..... replace x with 1; replace y with 4
-3 + 4 = 1
1 = 1
The answer is confirmed.
If you were to graph -3x + y = 1, which is equivalent to y = 3x+1, you'll find that the point (1,4) is on this line.
