Question

Use the substitution method to solve the system of equations.

4(x-2)=8(y-1)
16y-32=2x+4

Write answer as an ordered pair.

Answer 1

4(x-2)=8(y-1) 16y-32=2x+4
solve the bracket
4x - 8 - 8y - 8
now you can do the problem
hope it helped

Answer 2

So then it would be -4x-16y right?

Answer 3

Thanks for helping me if you are texaschic

Answer 6

4(x - 2) = 8(y - 1) --- distribute through the parenthesis
4x - 8 = 8y - 8
4x - 8y = -8 + 8
4x - 8y = 0

16y - 32 = 2x + 4
-32 - 4 = 2x - 16y
- 36 = 2x - 16y --- reduce
-18 = x - 8y

now we have :
x - 8y = -18 ----> x = 8y - 18
now sub 8y - 18 in for x in the other equation

4x - 8y = 0
4(8y - 18) - 8y = 0
32y - 72 - 8y = 0
24y = 72
y = 3
now sub 3 in for y in either equation to find x
x - 8y = -18
x - 8(3) = -18
x - 24 = -18
x = -18 + 24
x = 6

check..
4x - 8y = 0
4(6) - 8(3) = 0
24 - 24 = 0
0 = 0 (correct)

solution : (6, 3)

any questions ?
