2x + 3y = 29 and y = x + 3, what is the value of x?

A) 4
B) 5

C) 6
D) 7

Correct answer:
A) 4

Description for Correct answer:
2x+3y = 29 ...(i)

and y = x+3 ...(ii)

Putting the value of y from Eq. (i) to Eq. (ii), we get

2x+3y = 29

\( \Large 2x+3 \left(x+3\right)=29 \)

2x+3x+9 = 29 = 5x = 20

Therefore, x = 4
