What is the answer to 10x plus 2 equals 7?

i think its x= 2 10x+2=7 then you have to get rid of the numbers by its self on the x's side so you would subtract 2 from 7 and get 10x=5 then you have to divide it and it becomes x=2


What is the slope of the line 10x plus 5y equals 25?

10x - 8y equals -2 9x plus 8y equals 59?

Do a bit of rearrangement: 1: 10x + 2 = 8y; 2: 8y = 59 - 9x so 10x + 2 = 59 - 9x so 19x - 57 making x = 3 and y is therefore 4.


10x-18 equals 5x plus 2?
