A.3x+2(x+5)=40
3x+2x+10=40
5x=40-10=30
x=30/5=6
B.8x+2(x-2)=35-3x
8x+2x-4=35-3x
10x+3x=35+4
13x=39
x=39/13
x=3
Answer :
(B) option is correct bcozz 3is coming
Answer:
Option (B) is the right answer.
Step by step explanation:
8(x) + 2 (x-2) = 35 - 3x
= 8(3) + 2 (3-2) = 35 - 3(3)
= 24 + 2(1) = 35 - 9
Hence, 26 = 26.
