What is the value of the x-coordinate of 2x+3y=144; y-x=24

The x-coordinate of the solution of the system is x=14.4

Step-by-step explanation:

The question is

What is the x-coordinate of the solution of the system of equations?

we have

----> equation A

---> isolate the variable y

----> equation B

Solve the system by substitution

substitute equation B in equation A

solve for x

Apply distributive property

Combine like terms left side

subtract 72 both sides

Divide by 5 both sides

therefore

The x-coordinate of the solution of the system is x=14.4

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.
