Question

6x+4x+3y+30=50+2y+3y.If X=4 then y=?​

Answer 1

Answer:

6x+4x+3y+30=50+2y+3y

10x+3y+30=50+5y

10x+3y=50-30+5y

10x+3y=20+5y

10x=20+5y-3y

10x=50+2y

10×4=50+2y (given x=4)

40=50+2y

40-50=2y

-10=2y

2y= -10

y= -10/2

y= -5 answer

Answer 2

Answer:

y = 10

Step-by-step explanation:

$6x+4x+3y+30 = 50+2y+3y$

or $10x+3y+30 = 50+5y$

or $10x+30-50 = 5y-3y$

or $10x-20 = 2y$

∵ $x=4$ ⇒ $(10*4)-20 = 2y$

or $40-20 = 2y$

or $20 = 2y$

or $y = 10$
