The answer to the question
6x=18 (2x+5) x=6x+15. x-15=6x 5x=15 x=3
Answer:
Option (2)
Step-by-step explanation:
Given expression is, AX + B = C



AX + B = C
AX = C - B
C - B =
= 
C - B = 
Let 
AX =
= 
Since AX = C - B

Therefore, a = 1, b = 5
(-3a - 4c) = -35
3(1) + 4c = 35
3 + 4c = 35
4c = 32
c = 8
And (-3b - 4d) = -11
3(5) + 4d = 11
4d = -4
d = -1
Therefore, Option (2). X =
will be the answer.
