Solution:

5x = 30 +5

5x = 35

X = = 7

A) {30}B) {34}C) {11}D) {7}

Solve and check the linear equation.9x - (7x - 1) = 2

Solution:

9x- 7x +1 = 2

2x + 1 = 2

2x = 2 - 1

2x = 1

X =

A) B) C) D) 

Solve and check the linear equation.7x - 9 = -10 + 4x

Solution:

7x - 4x = -10 + 9

3x = -1

X =

A) B) C) D) 

Solve and check the linear equation.(-5x + 4) - 5 = -4(x - 7)

Solution:

-5x + 4 - 5 = -4x + 28

-5x - 1 = -4x + 28

-5x + 4x = 28 + 1

-x = 29

X = - 29

A) {19}B) {- 6}C) {29}D) {- 29}

Solve and check the linear equation.-3x + 5 + 6(x + 1) = -2x + 3

Solution:

-3x + 5 + 6x + 6 = -2x + 3

3x + 11 = -2x + 3

5x = 3 - 11

5x = -8

X=

A)  B)  C) D)  

Solve and check the linear equation.6[-6x + 6 + 4(x + 1)] = 6x + 2

Solution:

-36x + 36 + 24x + 24 = 6x + 2

-12x + 60 = 6x + 2

-6x = 2 - 60

-6x = -58

X = =

A)  B) C)  D)  

Solve and check the linear equation.32 - 2(11 - 8)2 = 36x

Solution:

9 - 2(9) = 36x

9 - 18 = 36x

-9 = 36x

X =

X =

A) B) {4}C) D) {0}

Solve and check the linear equation.0.30(80) + 0.60x = 0.40(80 + x)

24 + 0.60x = 32 + 0.40x

24-32 = 0.40x - 0.60x

-8 = -0.20x

X =

X = 40

A) {20}B) {30}C) {50}D) {40}

Solve and check the linear equation.0.40x - 0.20(50 + x) = -0.04(50)

0.40x - 10 - 0.20x = - 2

0.20x = -2 + 10

0.20x = 8

X =

X = 40

A) {50}B) {30}C) {40}D) {20}

Solve the formula for the specified variable.F = C + 32for C

Solution:

F - 32 = C

C = (F - 32)

A) C = (F - 32)B) C = C) C = D) C = (F - 32)

Solve the formula for the ...
