Answer:
Slide 1 answer:B: p=-6
Slide 2 answer : C: x=0
Slide 3 answer: A: a=0
Step-by-step explanation:
You can do this two ways.
Way 1: plug in that answer choices to your equation and see if one of them makes the equation true
or
Way 2: isolate varable and do sadmep... reverse operations.
I will use anyone that best suits you but i will use way 2.
5p-14=8p+4
move 5p by subtracting on both sides
-14=8p-5p+4
-14=3p+4
now subtract 4 from both sides
-14-4=3p
-18=3p
now divide 3 on both sides to isolate p
-18/3=p
p=-6
Slide 2:
for this one i will just plug in answers to see which one makes the statement correct
12=-4(-6(1)-3)
12=-4(-6-3)
12=-4(-9)
i already know its incorrect because -4*-9 is a way higher number then 12
so x=1 is incorrect
lets try x=0
12=-4(-6(0)-3)
12-4=(-6*0=0 -3)
12=-4(-3)
12=12
so x=0 is correct
Slide 3:
For this one as well i will plug in the answers to see which one makes the statement true.
a=0
0+5=-5(0)+5
5=5
this statment is true so
a=0 is correct
