Question

if 4x-3y +2a=2 for x =(-2) and y=2, find the value of 'a'​

Answer 1

Step-by-step explanation:

$4x - 3y + 2a = 2 \\ 4( - 2) - 3(2) + 2a = 2 \\ - 8 - 6 + 2a = 2 \\ 2a = 2 + 14 \\ a = \frac{16}{2} \\ a = 8$

Answer 2

Answer:

$x = - 2 \\ y = 2 \\ \\ 4x - 3y + 2a = 2 \\ 4( - 2) - 3(2) + 2a = 2 \\ - 8 - 6 + 2a = 2 \\ - 14 + 2a = 2 \\ 2a = 2+ 14 \\ 2a = 16 \\ a = \frac{16}{2} \\ \boxed{a = \underline{ \underline{ \bf8}}}$
