TiliK225 [7]

remember that you have to do the same to both sides

\frac{x}{4}+16>34

minus 16 both sides

\frac{x}{4}+16-16>34-16

\frac{x}{4}+0>18

\frac{x}{4}>18

mulitply both sides by 4

\frac{4x}{4}>18*4

(x)(\frac{4]{4})>72

(x)(1)>72

x>72

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

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
