Answer: The first one is 144 . The second one is C.
Step-by-step explanation:
You have to have one side equal x so I’ll solve one from each section
e) x = 2
5x = 12 - x
add x to both sides
6x = 12
divide both sides by 6
x = 2
k) x = 3
15x + 4 = 10x + 19
move the 4 to the other side by subtracting on both sides
15x = 10x + 15
subtract 10x from both sides
5x = 15
divide by sides by 5
x = 3
