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

The value of x - coordinate is 14.4

Solution:

Given that we have to find the x -coordinate of the system

Given system of equations are:

2x + 3y = 144 eqn 1

y - x = 24 eqn 2

Solve the above system of equations to find the x - coordinate

From eqn 2,

y = 24 + x eqn 3

Substitute eqn 3 in eqn 1

2x + 3(24 + x) = 144

2x + 72 + 3x = 144

Add the like terms

5x + 72 = 144

5x = 144 - 72

5x = 72

Divide 72 by 5

x = 14.4

Thus the x - coordinate of the system is 14.4

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4
