For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.

Answer:
60=3/4
x=4/4
4/4÷1/4
4/4*4/1
4/1*1/1
4/1
4
3/4=12 because if 1/4 is 4 then 3/4 is 12
60=12
60÷12=5
5*4/20
60+20=80

Step-by-step explanation:
the first number, 2, represents how many wholes are in the group, beings it is separated from the rest of the fraction by a space
the 2/3 is the fraction itself, in this case the last number, 3, is how many pieces the new whole is divided into, wile the first part is how many of those pieces are there
