by studying because that's the hard truth
Answer:
(6,4)
Step-by-step explanation:
y = x-2
y =4
Set the two equations equal
x-2 =4
Add 2 to each side
x-2+2 = 4+2
x =6
Now we need to find y
y =4
(6,4)
Answer with Step-by-step explanation:
We are given an expression:
28 + x - 2n + 7 - n - 5x + 4
We have to find its equivalent expression
On combining the like terms of the above expression
28+4+7+x-5x-2n-n
= 39-4x-3n
= -3n-4x+39
According to Tyrone the equivalent expression was:
-3n - 5x + 39 + x
The error Tyrone made was:
A. Tyrone neglected to combine the x terms
<h3>
Answer: Choice B) -4 < x < 2</h3>
Work Shown:
-1 < x+3 < 5
-1-3 < x+3-3 < 5-3 ... subtract 3 from all sides
-4 < x < 2
