Lets make the cost of the algebra textbook = x and the cost of the geometry book = y

2x+3y=64
4x+2y=66

now we get one of these equations in terms of one variable

2x+3y=64 ---> 2x=64-3y ---> x=32-1.5y

now we can plug that numeric value back into the other equation

4(32-1.5y)+2y=66

we can now simplify this equation in order to get the value of y

4(32-1.5y)+2y=66 ---> 128-6y+2y=66 ---> 128-4y=66 ---> -4y=-64 ---> y=16

What is the value of x????
inysia [295]

If QR is a median, then:

\dfrac{NO+MP}{2}=QR

We have NO = 30, MP = 9x - 42 and QR = x + 15. Substitute:

\dfrac{30+9x-42}{2}=x+15\qquad\text{multiply both sides by 2}\\\\9x-12=2x+30\qquad\text{add 12 to both sides}\\\\9x=2x+42\qquad\text{subtract 2x from both sides}\\\\7x=42\qquad\text{divide both sides by 7}\\\\\boxed{x=6}
