Question

(b) 2x + 9 = 3(x – 5). 7​

Answer 1

Hello friend, here is your answer :

2x+9=3x-15*7 (distributing 3 to numbers in bracket)

2x-3x= -15*7-9 (bringing all x to one side)

-x= -114

Therefore, x=114 (removing '-' sign from both sides)

Hope it helps

:)

Answer 2

Step-by-step explanation:

2x+9=3(x-5).7

2x+9=3x-15.7

2x+9=3x-105

2x-3x=-105-9

-x=-114

x=114
