Question

A few math 8th grade problems Please help me. PLEASE! Solve the system of equations. Use the substitution method to solve.


4x – 2y = 24


x – y = 3

Answer 1

Since you have
x - y = 3
you can say that x = y+3
then substitute on first equation the x for (y+3), to find value of y

Answer 2

Ok?

Answer 3

What next then?

Answer 4

Ive, what next?

Answer 5

x - y = 3 ---> x = 3 - y
now sub 3 - y in for x in the other equation
4x - 2y = 24
4(3 - y) - 2y = 24
can you take it from here ?
