Question

y = x - 2
7y - 4x = 10

Answer 1

Do you have to find using elimination using multiplication?

Answer 2

y = x - 2
7y - 4x = 10 Use addition or substitution to find the value of y for this set of equations.

Answer 3

first equ can be re written as
7y=7x-14 or 7y-7x=-14

7y-7x=-14
7y-4x=10
(subtracting the above two equation)
-3x=-24
x=8
now y=x-2
y=8-2=6
thus x=8 and y=6

Answer 4

Use addition or substitution to find the value of y for this set of equations.
x + y = 14
x = 6y

Answer 5

I would use the substitution method...You already know that y = x - 2. Now substitute x - 2 in for y in the 2nd equation. :)
