Answer:
x=10
Step-by-step explanation:
1) combine ALL like terms
5x-4+5x-4+3x+58=180
5x+5x+3x=13x
-4-4+58=50
13x+50=180
2) subtract both sides by 50
13x+50-50=180-50
13x=130
divide both sides by "13"
x=10

The value of x - coordinate is 14.4
<em><u>Solution:</u></em>
Given that we have to find the x -coordinate of the system
<em><u>Given system of equations are:</u></em>
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
