Question

Solve this problem please. x+20<75

Answer 1

x<55

Explanation:

x+20=75

treat it like a pre algebra problem

x=55

then turn it into a inequality

x<55

that's your answer

Answer 2

X<55

Explanation:

X+20<75

Substrate 20 from both sides

X<55

Therefore the answer is X<55

But if there's a negative sign in front of the 55 the sign in front of X will surely change,that is,X>55 but since the 55 is positive.. the sign still remains x<55
