A linear equation is a equation that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
A system of linear equations is a collection of at least two linear equations.
In this case, the system of equations is given as
y = 4x + 8
4y = 4x - 8
Substitute y = 4x + 8 in 4y = 4x - 8
4(4x + 8) = 4x - 8
Expand the equation
16x + 32 = 4x - 8
Evaluate the like terms
12x = - 40
Divide by 12
x = -10/3
The above means that the number of solutions to the system is 1
