Multiply (x+3)(3x+8) x times 3x =3x^2 then multiply x times 8 = 8x
keep multiplying 3 times 3x =9x then 3 times 8=24
then multiply the -3x(x+3)= -3x^2-9x
your hole expression will look like this 3x^2+8x+9x+ 24-3x^2-9x
if you need to simplify you can do by adding or subtracting them.
for example you can add 8x+9x= 17x
Since it is the midpoint we can say:
12x - 1 = 8x +11
All we have do to is get all the x's alone on one side
12x - 1 = 8x + 11
12x = 8x + 12 (add both sides by 1)
4x = 12 (subtract both sides by 8x)
x = 3 (divide both sides to get what x is)
Answer:
x=1
Step-by-step explanation:
Substitute the value of y to the first given
3x+4(-x)=-1
3x+(-4x)=-1
-x=-1
divide both sides by -1
x=1
