7x+4=11​

Answer 1

Answer:

7x + 4 = 11

7x = 11 - 4

7x = 7

x = 1

Verification:

7 × 1 + 4 = 11

7 + 4 = 11

11 = 11

Answer 2

$\mathfrak \red{verification : }$

$7x + 4 = 11 \\ 7x = 11 - 4 \\ 7x = 7 \\ x = \frac{7}{7} \\ x = 1 \\ \tt \purple{substitution : } \\ 7(1) + 4 \\ 7 + 4 = 11 \\ 11 = 11 \\ \fbox \green{hence \: verified }$
