Question

solve the equation and check your solution by substituting in the equation 7x+2=-19

Answer 1

7x + 2 = -19
7x = -19-2 = -21
x = -21/7 = -3

x = -3

VERIFICATION

7x + 2 = -19
Putting x = -3

(7 × -3) + 2 = -19
-21 + 2 = -19
-19 = -19

Hence, verified.

Answer 2

$\huge\red{Answer\:is}$

$7x + 2 = - 19 \\ 7x = - 19 - 2 \\ 7x = - 21 \\ x = \frac{ - 21}{7} \\ x = - 3 \\ \\ now \: check \: it \: \\ 7( - 3) + 2 \\ = - 21 + 2 \\ = - 19 \: \: proved$
Hope it helps you
