Answer:
So the vaule of y is 7, 10 & 13
Step-by-step explanation:
Given that y = 3x+1 . So we can just substitute x-value into the equation :
Let x=2,
y = 3(2)+1
= 7
Let x=3,
y = 3(3)+1
= 10
Let x=4,
y = 3(4)+1
= 13
The answer is 5/7. That is the answer :)
If you would like to know what is y when x = 42, you can calculate this using the following steps:
x = 8 ... y = 20
x = 42 ... y = ?
8 * y = 20 * 42 /8
y = 20 * 42 / 8
y = 105
The correct result would be: y = 105 when x = 42.
Answer: " 4x + 2xy - 7pq " .

Explanation:
___________________________________
Given: " <span>4x - 7xy + 9xy - 7pq " ; Simplify the expression;
___________________________________
Combine the "like terms:
___________________________________
-7xy + 9xy = 2xy ;
___________________________________
Now, rerewrite the expression, substituting the "-7xy + 9xy"; with " + 2xy" ;
___________________________________
</span>→ " 4x + 2xy - 7pq " .
