Question

solve the system of equations
2x=4x-16
5y=4x+8

Answer 1

-2x = 16
x = 8

5y = 4(8) + 8
5y = 40
y = 40/5
y = 8

Answer 2

the top one which was my mistake is 2y=4x-16

Answer 3

2y = 4x - 16
y = (4x-16)/2
y = 2x - 8

5 (2x -8) = 4x + 8
10x - 40 = 4x + 8
6x = 48
x = 48/6
x = 8

y = 2 (8) - 8
y = 8

Answer 4

thank you :)

Answer 5

you are welcome!

Answer 6

can you help me with this one.?
9x-3y=36
7x-3y=45
