Question

Need help.Cant get the right answer!

Answer 1

$\huge \boxed { \sf Solution}$

1. 14 - 4x = 26

or, -4x = 26 - 14

or, -4x = 12

or, x = 12 ÷ (-4)

or, x = -3

2. (x + 18)/4 = 5

or, x + 18 = 5 × 4

or, x + 18 = 20

or, x = 20 - 18

or, x = 2

3. 20x - 2 = 8

or, 20x = 8 + 2

or, x = 10/20

or, x = 1/2

4. 1 + 33x = 12

or, 33x = 12 - 1

or, 33x = 11

or, x = 11/33

or, x = 1/3

1. x = -3. The letter is F.

2. x = 2. The letter is H.

3. x = 1/2. The letter is D.

4. x = 1/3. The letter is A.

So, the letter code is FHDA.

Answer 2

Answer:

FHDA

Step-by-step explanation:

1)

$14-4x=26\\-4x=26-14\\-4x=12\\x=\frac{12}{-4}\\x=-3$

The first answer is F.

2)

$\frac{x+18}{4}=5\\x+18=5\times4\\x+18=20\\x=20-18\\x=2$

The second answer is H.

3)

$20x-2=8\\20x=8+2\\20x=10\\x=\frac{10}{20}$

Both the numerator and denominator here are multiples of 10, so you can simplify the fraction by dividing both by 10.

$x=\frac{1}{2}$

The third answer is D.

4)

$1+33x=12\\33x=12-1\\33x=11\\x=\frac{11}{33}$

Same as the last problem. Both are divisible by 11 so you can simplify the fraction by dividing both by 11.

$x=\frac{1}{3}$

The fourth answer is A.
