a million is A) with the aid of fact it somewhat is actual... 2 is D) with the aid of fact whilst u subtract a million from the two sides u get -6 < x or x > -6 3. 3(x+2) < 2x + 10 enhance brackets 3x + 6 < 2x +10 subtract 2x from the two sides x + 6 < 10 subtract 6 from the two sides x < 4 4. is B) considering whilst u divide by utilising -5 u opposite the sign and get x >/ -5
5x-3>2
Move the -3 to the right hand side by adding 3 to both sides, like this:
To the left hand side:
-3 + 3 = 0
Okay now your equation should look like this
5x>2+3 = 5x>5
Next step, remember when your taking a number from one side to the other you must change the sign. So the 5 becomes negative, Very important.
so, 5x>5
divide the negative 5 to the other side.
Your answer would be (D)
= x>1
D. 5x > 5...
x>1
