You should first fully understand what an equivalent expression is. This type of expression is an equation that are the same, even though they might look a little different at first glance. When you try to substitute a value to the expression, they will result in the same value at the end.

Answer:
Y=3
X=9/5
Step-by-step explanation:
(1) 5x=y+6
(2) 5x+2y =3
Replace (1) to (2) => (y+6)+2y=3 => y=3
Replace y=3 to (2) => 5x = 3+6 => 5x=9 => x=9/5
Answer:
2(x - 8) = 2x - 16
2(-8) + x + x = -16 + 2x or 2x - 16
2(3x + 2) = 6x + 4
6x - 2(2x + 8) = 2x + 8
-2(-3x - 2) = 6x + 4
-2(-x + 8) = 2x + 16
-14 + 3 + 2(9) + 3x = 7 + 3x
2x + 2(2x + 2) = 6x + 2

Answer and Step-by-step explanation: <u>Law</u> <u>of</u> <u>deduction</u> is a mathematical logic that states the following:
1) If p happens, then q happens;
2) p is true;
Then, a there is a third statement that is
3) q is also true.
In this question,
If a polynomial is prime, then it cannot be factored.
Statement p is that 5x + 13y is a polynomial and is prime, i.e., p is true.
Statement q is that "it cannot be factored"
Therefore, 5x + 13y cannot be factored.
