Answer:
x = 60
Step-by-step explanation:
t = 
15 = k/68 
k=1020
~~~~~~~~~~~
17 = 1020/x
x = 1020/17
x = 60

<h2>
Step-by-step explanation:</h2>
<em>(Solving for x on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -3y to both sides.
2x + 3y + −3y = 32 + −3y
2x = −3y + 32
Step 2: Divide both sides by 2.

<u>x =  </u> <u>⁻y + 16</u><u>                                                                                                                 </u>
<u>⁻y + 16</u><u>                                                                                                                 </u>
<em>(Solving for y on question - 2x + 3y = 32)</em>
2x + 3y = 32
Step 1: Add -2x to both sides.
2x + 3y + −2x = 32+ −2x
3y = −2x + 32
Step 2: Divide both sides by 3.

<u>x + </u> <u>                                                                                                           </u>

<em>(Solving for x on question - 5x - 4y = -81)</em>
5x − 4y = −81
Step 1: Add 4y to both sides.
5x − 4y + 4y = −81 + 4y
5x = 4y − 81
Step 2: Divide both sides by 5.
 =
 =   
<u>x =  </u> <u>y + </u>
<u>y + </u> <u>                                                                                                               </u>

<em>(Solving for y on question - 5x - 4y = -81 )</em>
5x − 4y = −81
Step 1: Add -5x to both sides.
5x − 4y + −5x = −81 + −5x
−4y = −5x − 81
Step 2: Divide both sides by -4.
 =
 =  
y =   x +
