infinitely many solutions
we have been given the equation;
2(2x + 3) = -4 + 2(2x + 5)
we need to determine the value of x.
2(2x + 3), we expand this expression to obtain 4x + 6
similarly 2(2x + 5) will become 4x + 10
now we have;
4x + 6 = -4 + 4x + 10
4x + 6 = 4x + 10 - 4
4x + 6 = 4x + 6
the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;
y = 4x + 6
consequently, we shall have infinitely many solutions
