Solving the first equation:(234+x) - 456 = 178234 + x - 456 = 178x - 222 = 178x = 178 + 222x = 400
Solving the second equation:7000 - (5210-x) = 45697000 - 5210 + x = 45691790 + x = 4569x = 4569 - 1790x = 2779
Therefore, the solutions are:x = 400 for the first equationx = 2779 for the second equation
Solving the first equation:
(234+x) - 456 = 178
234 + x - 456 = 178
x - 222 = 178
x = 178 + 222
x = 400
Solving the second equation:
7000 - (5210-x) = 4569
7000 - 5210 + x = 4569
1790 + x = 4569
x = 4569 - 1790
x = 2779
Therefore, the solutions are:
x = 400 for the first equation
x = 2779 for the second equation
