Remember
we can do anything to an equation as long as we do it to both sides
try to isolate the variable
you have 2 types
x+b=c
x/b=c
fior the first type, minus b from both sides to get
x=c-b
for the second, multiply both sides by b to get rid of the fraction to get
x=cb
also remember that -x times -1=x
b.add 25 to both sides
-a=20
multiply -1
a=-20
c.
-t/8=-4
multiply both sides by 8
-t=-32
mutiply -1
t=32
d. -n/-5=-30
mulitply both sides by -5
-n=150
multiply both sides by -1
n=-150
e. multiply both sides by 12
-l=144
multiply b y-1
l=-144

Answer:
218
Step-by-step explanation:
help me on my recent
Add together to get -3
Multiply together to get -10
Can you think of the two numbers?
Try 2 and -5:
2+-5 = -3
2*-5 = -10.
Therefore, (x+2)(x-5) is the answer :)
Answer:
310%
