Question

389+( х-47) =819 ( х+631)-567=666

Answer 1

Х+631-567=666
х=666-64
х=602

Answer 2

Let's solve the equations step by step:

1. 389 + (x - 47) = 819

Let's simplify the equation:

389 + x - 47 = 819

Combine like terms:

x + 342 = 819

Subtract 342 from both sides:

x = 819 - 342

x = 477

So the solution for the first equation is x = 477.

2. (x + 631) - 567 = 666

Let's simplify the equation:

x + 631 - 567 = 666

Combine like terms:

x + 64 = 666

Subtract 64 from both sides:

x = 666 - 64

x = 602

So the solution for the second equation is x = 602.

Therefore, the solutions for the given equations are x = 477 and x = 602.
