Question

-2(y+3)=7 find equation and check your answer {Class-7}
​

Answer 1

Answer:

y= -13/2

Step-by-step explanation:

-2y-6=7

-2y=7+6

-2y=13

y=-13/2

Answer 2

Step-by-step explanation:

-2(y + 3) = 7

-2y -6 = 7 [Multiplying -2 with y and 3]

-2y = 7+6

-2y = 13

y =13/-2

check

-2 (13/-2 +3 )=7 [ putting The value of y i.e 13/-2]

-2 ( 13 -6 /-2) =7 [ CROSS MULTIPLYING 13 WITH 1(Denominator of 2 ) AND 3 WITH -2 And the MULTIPLYING both the denominatorsi.e 2 and 1 ]

-2 (7/-2) = 7 (Here the -2 and i.e outside of the bracket and -2 i.e denominator of 7/-2 gets cancelled)

7=7
