Answer:
<h2>3</h2>
Step-by-step explanation:

Both equations are equal to y, so set them equal to each other forming an equation in x
2x+4=x-3
-x -x
1x+4= -3
-4 -4
x= -7
You just plug in the value of x which is -7
Y= -7-3
Y= -10
Answer:
Any multiple of 10
Step-by-step explanation:
A factor is defined as "a number or quantity that when multiplied with another produces a given number or expression." For example, the factors of 20 are 1, 2, 4, 5, 10, and 20.
When we multiply 2 and 5 together, we get 10. Multiplying this by anything else besides 0 will still yield something that has 2 and 5 as factors, for example 2 times 5 times 3 is 30. As this is just the same thing as multiplying 10 by 3, the answer is any multiple of 10.
