Answer:
D
Step-by-step explanation:
20x + 12 x =14x +30
20x - 14x = 30-12
6x= 18
6x/6 = 18/6
x = 3
so xs =3
Answer: it's A
Step-by-step explanation: Its A I bet nonono C
Solving inequalities is almost the same as solving equalities for basic cases. Only thing you've to watch out for is signs.
For example, in 2x + 3 > 5,
We may subtract 3 from both sides,
2x > 2
Hence, by dividing both sides by 2, we get x>1.
The inequality sign changes on multiplying with (-)
For example, 2 < 6
But, -2 > -6
And when you interchange a fraction
E.g. 3/4 > 2/3
But, 4/3 < 3/2
You can now solve these of your own
