7x =2(y+4)
7x-2y-8 and y= 7/2x -4
1) An equivalent number equation is an equation that has the same result on the right side.
In algebra, we can have equivalent equations by algebraic manipulation.
So for that:
7x-2y=8
We can say that, for example
7x =2(y+4) Factoring out 2y and 4
7x-2y-8=0 Placing the 8 on the left side of the equation
and
y= 7/2x -4 Writing that on the Standard linear equation form, dividing by 2
are Equivalent equations.
