Question

2 x + 3 y + 2 z in term of z and find the value of the expression when z is equal to2

p​

Answer 1

$= 2x + 3y + 2z \\ \\ \: where \: \: z = 2 \\ \\ = 2x + 3y + 2(2) \\ \\ = 2x + 3y + 4 \\ \\ 2x = 3y + 4 \\ \\ x = \frac{3y + 4}{2}$

Answer 2

Step-by-step explanation:

=2x+3y+2z

where

z=2

=2x+3y+2(2)

=2x+3y+4

2x=3y+4

x= 3y+4/2
