2x + 5 = 25 2x = 20x = 10
y = 2x18 = 2xIf both equation equals 2x on the right, the left must also equal.y=18

y = 2x + 1 IS a linear equation!
-2x plus 3y equals 1
yes
Yes.
Yes.

-2x + 8 = 7x - 10 is technically an equation, in and of itself.
x = 4 and y = 7
It is an equation and the value of x is 1
