Question

Make x the subject of the formula x(2+a)=b(x+3)

Answer 1

x( 2 + a ) = bx + 3b

x( 2 + a ) - bx = bx - bx + 3b

x ( 2 + a - b ) = 3b

x ( 2 + a - b ) ÷ ( 2 + a - b ) = 3b ÷ ( 2 + a - b )

x = 3b / 2 + a - b

Answer 2

x=3b/(2+a-b)

Explanation:

x(2+a)=b(x+3)

2x+ax=bx+3b

2x+ax-bx=3b

x(2+a-b)=3b

x=3b/(2+a-b)
