If y-3=7 and x+3y=6 then x=?Show your work.

If y-3=7 and x+3y=6 then x=?


First let's find what " y " equals


y - 3 = 7 add 3 on both sides


By adding, you should get


y = 10 which is what " y " equals 


Now plug 10 into the equation


x + 3 ( 10 ) = 6 multiply 3 with 10


By multiplying,  you should get


x + 30 = 6 now subtract 30 on both sides


By subtracting, your equation should look like


x = -24 which Is your answer
