Math 8 Variables on both sides

-8m - 11 = 4m + 37

• m = 4

• m=12

• m=-4

• m= -12

19 - x = 30 - 2x

• x = 11

• x = -11

• x = 11/3

• x = - 11/3

-1/2k + 4 = 20

• k = -32

• k = -8

• k = 32

• k = 8

-5a + 6 = -9 a - 26

• a = 2

• a = 3

• a = 8

• a = -8

3(x + 2) = -2 (x + 16)

• x = -7.6

• x = 4

• x = 3.3

• x = 7.6

6 (x + 3) = 2 ( x + 2 )

• 3.5

-3x + 15 = 7x + 45

• -3

• 3

• 7

• 8

-2x - 5 = 3x + 16

• 7

• 6

• 4.2

• -4.2

What is the first step I should do: 5(x - 4) = -3x + 7

• subtract 3 from both sides

• add 4 to both sides

• distribute 5

• add 3x to both sides
