It is: y = -4x+12
Yes and t = 1 in both equations
Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
no.
2x+7=3 is an equation. However, 2x=-4 is equivalent. So is x=-2. And an infinite number of others.

3m + 11n = 3
Equivalent to what? "3x = 3 + x" is an equation which can be equivalent to other equations, but none is mentioned.
It is an equation and the value of a is 16
no.
An equation where X = 18

x=1
It is a linear equation in three variables which is equivalent to a linear equation in two variables. This is because 3 + e = 2.3f +e - 7g is equivalent to 3 = 2.3f -7g
An equation where q = 240
We have no clue what question that equation is asking.
