Answer:
the answer is x = 0
Step-by-step explanation:
Cancel equal terms on both sides of the equation:

Divide both side of the equation by 5.

Therefore, the answer is x = 0
So 15-7 is 8
Here are some things I did:
10-2 or 28-20
X = -17/8

Answer:
x = 11.5
Step-by-step explanation:

The number of hours Jeremiah ironed = 10 hours
The number of hours Tristan ironed = 7 hours
<u>Step-by-step explanation</u>:
- Jeremiah can iron = 35 shirts per hour
- Tristan can iron = 20 shirts per hour
- Total work done by both = 490 shirts
Let 'x' be the number of hours Jeremiah ironed.
Let 'y' be the number of hours Tristan ironed.
x+y = 17 ------(1)
35x + 20y = 490 -------(2)
Multiply (1) by 20 and subtract (2) from (1),
20x + 20y = 340
-(<u>35x + 20y = 490</u>)
<u>-15x = -150 </u>
x = 150/15
x = 10
Substitute x=10 in (1)
10+y = 17
y = 7
