X=2y-6;y=3x-7
substitution to solve systems of equations

As you said, we can solve this system for y by using substitution.

Now, using what we got for y, we plug it into one of the original equations to solve for x.

Now we have the solution of this system.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

it would be 3 ÷by 6 because the number on each side
