-17h=-204 . k/2=-27
Two Step
-3p+-8=31 W/6-9=-8
Variables on both sides
-2(-7x+4)=36 2y-(y-5)=9

Sagot :

-17h=-204
Divide both sides by -17. Which gives you h=12
K/2=-27 multiply both sides by 2. K=-54

-3p+-8=31
Add 8 to both sides. Which gives you -3p=39. Divide both sides by -3 and you get p=-13.
apologiabiology
not sure what that means but I will try to answer
things to remember:
when working with equations,  you can do anything to the equation, except divide by zero, as long as you do it to both sides.
you waant the placeholders on  one side and the numbers on the other
-17h=-204
multiply both sides by -1

17h=204
divide both sides by 17
h=12

k/2=-27
multiply both side by 2
2k/2=-54
k=-54

-3p-8=31
add 8 to both sides
-3p=39
divide both sides by 3
-p=13
multiply both sides by -1
p=-13

so this one is tricky
-2(7x+4)=36
2y-(y-5)=9
so if we simplify these equations we get
-2(-7x+4)=36
distribute
14x-8=36
add 8 to both sides
14x=44
divide both sides by 14 we get
x=44/14=22/7= 3 and 1/7

2y-(y-5)=9
remember that -(y-5)=-1(y-5) so
distribute
2y-y-(-5)=9
add like terms
y+5=9
subtract 5 from both sides
y=14
