5(x-1)+2(x+3)+6=0​

Answer 1

Answer:

= 1

Step-by-step explanation:

5 ( x- 1) +2( x+ 3) +6 = 0

5x - 5 + 2x+6+6 = 0

7x-5+6+6 = 0

7x + 7 = 0

7x = O + 7

7x= 7

x= 7 / 7

x= 1

This is correct

Answer 2

$\rm \underline{Solution : }$

$\sf{ : : : \mapsto5(x - 1) + 2(x + 3) + 6 = 0}$

$\sf{: : : \mapsto5x - 5 + 2x + 6 + 6= 0}$

$\sf{: : : \mapsto7x + 7 = 0}$

$\sf{: : : \mapsto7x = - 7}$

$\sf \purple{ : : : \mapsto \: x = \cancel \frac{ - 7}{7} = - 1}$

$\rm \underline{Verification :}$

$\sf{: : : \mapsto5( - 1 - 1) + 2( - 1 + 3) + 6 }$

$\sf{: : : \mapsto5( - 2) + 2(2) + 6}$

$\sf{: : : \mapsto - 10 + 4 + 6}$

$\sf{: : : \mapsto - 10 + 10}$

$\sf \pink{: : : \mapsto 0}$

$\sf \green{Hence, Verified \: \checkmark}$
