anonymous · Answer

Instead of an 'x', put in 'y-6' into the first equation.  Use brackets to stay organized.
5(y-6) + 10y = 18
Then you can expand it.

a) 5x + 10y - 6 = 18

b) 5y - 6 + 10y = 18

c) 5y - 30 + 10y = 18

texaschic101 · Answer

5(y - 6) + 10y = 18...
this is the same as :
5 * y - 5 * 6 + 10y = 18
can you do it now ?
