Answer:

x...third number

4x...second number

x-9...first number

(x)+(4x)+(x-9)=141

x+4x+x-9=141

6x-9=141

Let's add 9 to both sides...

9+6x-9=141+9

6x=150

Let's divide both sides by 6...

(6x)/6=150/6

x=25

third number...25

second number...(4)(25)=100

first number...(25-9)=16

Let's check our work...

25+100+16=141

141=141

How to solve -d/6+12=-7
Delicious77 [7]
IF you are solving for d:

isolate the D, do the opposite of PEMDAS.

-d/6 + 12 = -7

(subtract 12 from both sides)

-d/6 + 12 (-12) = -7 (-12)

-d/6 = -19

(multiply 6 to both sides)

-d/6(6) = -19(6)

-d = -19(6)

-d = -144

-d/-1 = -144/-1

d = 144

hope this helps
