Answer:
substitution method is tricky until u get the hang of it. 6y=x so 3x-8y=-50 can be rewritten as 3(6y)-8y=-50.
Step-by-step explanation:
3x-8y=-50.........(1)
6y= x ..............(2)
Substituting x = 6y in (1)
3(6y) - 8y = -50
multiply 3(6y)
18y - 8y = -50
subtract 8y from 18y
10y = -50
divide to get y alone
y = -50/10
y = -5
now substitute. you know what y is. 6y=x / 6(-5)=x
solve :)
6y = x
6(-5) = x
-30 = x
x = -30
