Question

Solve the system of equations. Use the substitution method to solve.
4x – 2y = 24

x – y = 3

Answer 1

take -2y in right hand side

Answer 2

4x – 2y = 24

x – y = 3 ----> x = 3+y = y+3


4x – 2y = 24
4(y+3) – 2y = 24
4y+12 – 2y = 24
2y+12 = 24
2y= 12
y=6

can you solve for x ?

Answer 3

Thank you.

Answer 4

You welcome !

Answer 5

if it makes it any easier for you, the first equation..4x - 2y = 24 can reduce to 2x - y = 12.
It will probably make it a little easier using smaller numbers

Answer 6

Ok thank you.

Answer 7

sure thing :)
