Question

5(y – 4) -2(y - 9) + 5(y + 6) = 0​

Answer 1

Answer:

3.5 answer.

Step-by-step explanation:

5y-20-2y+18+5y+30= 0

5y-2y+5y-20+18+30= 0

8y +28 =0

8y = -28

y = -28/8 = 3.5 answer

Answer 2

Answer:

Given:-

5(y-4)-2(y-9)+5(y+6)=0

Solution:-

5(y-4)-2(y-9)+5(y+6)=0

=5y-20-2y+18+5y+30=0

= 8y+28=0

= 8y= -28

$y = \frac{ - 28}{8}$

$y = \frac{ - 7}{2}$

y= -3.5 or -7/2

Verification:-

5(y-4)-2(y-9)+5(y+6)=0

5(-3.5-4)-2(-3.5-9)+5(-3.5+6)=0

5( -7.5) -2( -12.5)+5(2.5)=0

-37.5+25+12.5=0

-37.5+37.5=0

0=0

Since,

LHS=RHS

Hence,

The given solution:-

$x = \frac{7}{2} \: \: or \: \: 3.5$
