Answer:
x = -2
Step-by-step explanation:
x + 6 = 4
x + 6 - 6 = 4 - 6
1 Add 66 to both sides.
x=4+6x=4+6
2 Simplify 4+64+6 to 1010.
x=10x=10
{ solution is attached below}
Answer:96
A; 480/16 = 30 students per classroom
B: 192/12 =16 students per classroom
we need x such that
which means
(480-x )* 12 should be equal to (192+x) * 16
5,760 - 12x = 3,072+16x
5,760 - 3,072 = 12x + 16x
2,688 = 28x
x = 96
First number=6
Second number=14
Let the first number be x
So the second number is x+8
So the sum of the two is
X+x+8=20
2x+8=20
2x=20-8
2x=12
X=12/2
=6
The second number will x+8
So 6+8=14
