Question

Solve and verify your result:

(b) 5(x - 1) + 2 (x + 3) + 6 = 0​

Answer 1

Answer:

$5(x - 1) + 2(x + 3) + 6 = 0 \\ \\ 5x - 5 + 2x + 6 + 6 = 0 \\ \\ 7x + 7 = 0 \\ \\ 7x = - 7 \\ \\ x = \frac{ - 7}{7} \\ \\ x = - 1$

Answer 2

Answer:

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

= 5x + 2x - 5 + 12 = 0

= 7x + 7 = 0

= 7x = 0 - 7

= x = - 7/7

= x = -1

Check:-

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

= 5*-2 + 2*2 + 6 = 0

= -10 + 4 + 6 = 0

= -10 + 10 = 0

= 0 = 0
