Question

if A=× 2yand B= y -2× find the sum of 2A +3B​

Answer 1

Answer:

A=x+2y

then

2A=x+2y=

$\frac{x + 2y}{2}$

B=y-2x

then

3B=y-2x=

$\frac{y - 2x}{3}$

2A+3B=

$\frac{x + 2y}{2} + \frac{y - 2x}{3 } \\ = \frac{3x + 6y + 2y - 4x }{6} \\ = \frac{8y - x}{6} \\ = 8y - x = 6$

I hope it's help
