Question

2y + 5
y +4
= 1 solve the following equation and check your solution​

Answer 1

Answer:

2y+5y+4=1

    7y +4 = 1

        7y  = -3

          y = -3/7

checking the solution

=   2(-3/7)+5(-3/7)+4

=   -6/7 -15/7+4

=    -6-15/7  +4

=   -21 /7 +4

=         -3+4

=1    

hence we got the correct answer

       

Answer 2

Answer:

2.6

Step-by-step explanation:

2y + 5 +  y + 4 = 1

2y + y + 5 + 4 = 1

3y + 9 = 1

3y = 1-9

=-8

3y=-8

y =  minus 8 y  by 3

-8 ÷ 3

= 2.6
