4b+3=−9 i need help it is inportant

b=-3

Step-by-step explanation:

4b+3=-9

    -3   -3

subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.

4b=-12

youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4

4b/4=-12/4

4b divided by 4 is 1. -12 divided by 4 is -3

b=-3

plug -3 in for b to make sure its correct

4(-3)+3=-9

-12+3=-9

-9=-9

false

step-by-step explanation:

4y - 6 + 4y^2 - 9

4y -15 + 4y^2

it contains 3 terms
