Answer 1

Answer:

I hope this helps you

Step-by-step explanation:

7x =343

Therefore, x=343/7

=49

Answer 2

Your answer is 49

Step-by-step explanation:

7x = 343

x = $\frac{343}{7}$

x = 49

7 is taken to the other side is because, when multiplication taken to the other side will turn into division. for example: 7x = 21 ( 7x means 7 × X)

                                                                   x = $\frac{21}{7}$

                                                                    x = 3

same goes for addition and subtraction. When addition taken to the other side it becomes subtraction, for example: 5x + 4 = 29

                                                                        5x = 29 - 4

                                                                       5x =  25

                                                                         x = $\frac{25}{5}$

                                                                         x = 5

Example for subtraction:

4y - 5 = 21

4y = 21 - 5

4y = 16

y = $\frac{16}{4}$

y = 4

Example for division:

$\frac{15}{y}$ = 5

y = 15 x 5

y = 75

Hope you got it!
