No, an example would be 1 1/2* 1 1/2 or 3/2*3/2 if you did it the way mentioned above you would get 1*1+1/2*1/2 which is 1 1/4, however if we multiply correctly, 3/2*3/2 we actually get 9/4 which is equal to 2 1/4.
Should be 55 because they are inversely with x
4(x+2)=3(x-2)
Multiply the first bracket by 4
Multiply the second bracket by 3
4x+8=3x-6
Move 3x to the left hand side, whenever moving a number with a letter the sign changes ( positive 3x to negative 3x)
4x-3x+8=3x-3x-6
x+8=-6
Move positive 8 to the right hand side
x+8-8=-6-8
x=-14
Check answer by using substitution method
Use x=-14 into both of the equations
4(-14+2)=3(-14-2)
-56+8=-42-6
-48=-48
Answer is -14- D)
