Solution
3x - 4 + 4 = 11 + 4
3x = 15

Divide by 3

x = 5

Problem

Correct Answer

Your Answer

^-10 = 3m + 5

m =

Solution
^-10 - 5 = 3m + 5 - 5
^-15 = 3m

Divide by 3

^-5 = m

m = ^-5

Complexity=9, Mode=2

Solve.

Problem

Correct Answer

Your Answer

^-13 = 4e - 9

e =

Solution
^-13 + 9 = 4e - 9 + 9
^-4 = 4e

Divide by 4

^-1 = e

e = ^-1

Problem

Correct Answer

Your Answer

^-55 = 6g - 7

g =

Solution
^-55 + 7 = 6g - 7 + 7
^-48 = 6g

Divide by 6

^-8 = g

g = ^-8

Complexity=10, Mode=2

Solve.

Problem

Correct Answer

Your Answer

^-2y + 6 = ^-12

y =

Solution
^-2y + 6 - 6 = ^-12 - 6
^-2y = ^-18

Divide by ^-2

y = 9

Problem

Correct Answer

Your Answer

^-9u + 5 = ^-13

u =

Solution
^-9u + 5 - 5 = ^-13 - 5
^-9u = ^-18

Divide by ^-9

u = 2

Complexity=12, Mode=2

Solve.

Problem

Correct Answer

Your Answer

87 = 12t + 3

t =

Solution
87 - 3 = 12t + 3 - 3
84 = 12t

Divide by 12

7 = t

t = 7

Problem

Correct Answer

Your Answer

26 = ^-6z + 8

z =

Solution
26 - 8 = ^-6z + 8 - 8
18 = ^-6z

Divide by ^-6

^-3 = z

z = ^-3

Complexity=15, Mode=2

Solve.

Problem

Correct Answer

Your Answer

^-2e + 8 = ^-10

e =

Solution
^-2e + 8 - 8 = ^-10 - 8

Divide by ^-2

e = 9

Problem

Correct Answer

Your Answer

^-15 = 10f - 5

f =

Solution
^-15 + 5 = 10f - 5 + 5
^-10 = 10f

Divide by 10

^-1 = f

f = ^-1

Complexity=20, Mode=2

Solve.

Problem

Correct Answer

Your Answer

7u + 11 = ^-38

u =

Solution
7u + 11 - 11 = ^-38 - 11
