Question

find the value of v if the value of 9a -3b+6ab is -3 when a =-2​

Answer 1

Answer:

Hi

$9a - 3b + 6ab = - 3 \\ 9( - 2) - 3b + 6( - 2)b = - 3 \\ - 18 - 3b + ( - 12)b = - 3 \\ - 18 - 12b - 3b = - 3 \\ - 15b = \frac{ - 3}{ - 18} \\ b = \frac{1}{18 \times 15} \\ b = \frac{1}{270}$

may it will help you ☺️
