Question

If x = 14, which equation is true?

A 3(20- x) = 44
B 3(12-x) = 6
c 2(x - 3) = 22
D 2x-3 = 22
please I need help on this​

Answer 1

the answer would be 2(x - 3) = 22 (C)

Explanation:

step 1:

2(x - 3) = 22

step 2: divide both sides by the equation 2

x - 3 = 11

step 3: move constant (3) to the right and change its sign

x = 11 + 3

step 4: add the numbers (11 and 3)

x = 14

Answer 2

C

Explanation:

Simply plug in x for all the questions to see if the x is the solution

A.) 3(20-14) = 44

3(16)=48

so A is incorrect

B.) 3(12-14) = 6

3(-2) = -6

so B is incorrect

C.) 2(14-3) =22

2(11) =22

C is correct

D.) 2(14)-3=22

28-3 = 25

so D is incorrect
