Answer:
a = 9 / 7
step by step explanation:
9 / - a + 15 = 8
Determined the defined range
9 / ( - a ) + 15 = 8 , a ≠ 0
subtract 15 from each side
9 / - a + 15 - 15 = 8 - 15
calculate the difference
9 / - a = - 7
multiply both side of equation by - a
9 / - a × - a = - 7 × - a
9 = 7 a
divide each side by of equation by -7
9 / 7 = 7 a / 7
9 / 7 = a
swap the side of equation . ( optional )
a = 9 / 7
Answer:
x = 10
<u></u>
Step-by-step explanation:
2x - 4 = 16 try to get x on the left side, and the integers on the right
You then get:
2x = 20
Now, divide by 2 on both sides
2x/2 = 20/2
<u>x = 10</u>

Answer:
2n-8
Step-by-step explanation:
twice n is 2n. decreased by 8 is the -8
Kirk multiplied by 5.
-.25x • 4 = -1x
.2x • 5 = 1x
This causes the x terms to eliminate :)
