Which of the following gives a valid reason for using the given solution method to solve the system of equations shown? Equation 1: 4x - 5y - 4
Equation ll: 2x + 3y - 2
O Elimination; a coefficient in Equation II is an integer multiple of a coefficient in Equation I
O Substitution; equation I can be solved for x in one step by dividing both sides by 4.
O Elimination; a coefficient in Equation I is an integer multiple of a coefficient in Equation II.
O Substitution; equation Il can be solved for x in one step by subtracting 3y from both sides,

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
