answer plze 2d+36= -3d-54?

Answer 1

We need to collect the d terms on one side and the constants on the other. Remember that when you move something from one side to the other, you have to change it from positive to negative or from negative to positive:

2d + 36 = -3d - 54
=> 2d + 3d = -54 - 36
=> 5d = -90
=> d = -90 / 5
=> d = -18.

Answer 2

For this one you have to combine like terms. First do the letters. You have to add 3d to each side now the equation is 5d+36=-54. Then you combine the numbers by adding 36 to each side so now the equation is 5d=-90. The last step is -90 divided by 5=-18 so d=-18.

Answer 3

2d + 36 = -3d - 54
+2d + 36
<-d -18>

Answer 4

2d+36=-3d-54
2d+36+54=-3d-54+54
2d+90=-3d
2d-2d+90=-3d-2d
90=-5d
90/-5=d
-18=d

Just remember what ever you do to one side of the equation you have to to do the other. As long as you keep that in mind you will be ok....Oh and the variable stands alone, the variable stands alone...High ho the math-O the variable stands alone!

Answer 5

2d+36=3d-54
-2d from both sides:
36=1d-54
add 54 to both sides:
90=d(answer)
plug in to check answer:
2(90)+36=3(90)-54
180+36=270-54
216=216

Answer 6

2d + 36 = -3d - 54
2d + 3d = -54 - 36
5d = - 90
d = -90/5 = - 18

Answer 7

2d+36= -3d-54
2d+3d=-54-36
5d=-90;divide both terms by 5
d=-18

Answer 8

2d+36 = -3d-54
2d+3d+36-36=-3d-3d-54-36
5d=-90
5d/5=-90/5
d= -18

Answer 9

2d+3d=-54-36
or d=-90/5
d= -18

Answer 10

add 3d to both sides

5d+36=-54

Subtract 36 from both sides

5d=-90

Divide both sides by 5

d=-18
