Q: If 23+15 42+5 then %3D The value of x is

A: Given 23x+15 = 42x+5we know that 4=22so, 23x+15 =22(2x+5)⇒23x+15 =24x+10

Q: Identify the expression that is not equivalent to the others x-2+3x , 4(x-2) , -2+7x-3x , 4x-2

A: We have to simplify each expression.x-2+3x= 4x-2 (combined x+3x=4x)4(x-2) = 4x-8 (distributed 4)

Q: (-3,9) (-3,-5)

A: In (-3,9) and  (-3,-5) x ordinate = -3 for both.So on the line joining them x is fixed.
