2)124*2=248
3)635-114=521
4)905-521=384
5)384-248=136
Ответ:136







1) Let's solve the first equation step by step:
905 - (635 - 342/3) - 124 * 2
First, let's simplify the expression inside the parentheses:
635 - 342/3 = 635 - 114 = 521
Now, let's substitute this value back into the equation:
905 - 521 - 124 * 2
Next, let's perform the multiplication:
124 * 2 = 248
Now, let's substitute this value back into the equation:
905 - 521 - 248
Finally, let's perform the subtraction:
905 - 521 - 248 = 384 - 248 = 136
Therefore, the solution to the first equation is 136.
2) Now, let's solve the second equation step by step:
(3 * 100 - 200) * 4 + 20 + x + 30
First, let's perform the multiplication inside the parentheses:
3 * 100 = 300
Now, let's substitute this value back into the equation:
(300 - 200) * 4 + 20 + x + 30
Next, let's perform the subtraction inside the parentheses:
300 - 200 = 100
Now, let's substitute this value back into the equation:
100 * 4 + 20 + x + 30
Next, let's perform the multiplication:
100 * 4 = 400
Now, let's substitute this value back into the equation:
400 + 20 + x + 30
Next, let's perform the addition:
400 + 20 = 420
Now, let's substitute this value back into the equation:
420 + x + 30
Finally, let's perform the addition:
420 + 30 = 450
Therefore, the solution to the second equation is 450 + x.
I hope this helps! Let me know if you have any further questions.
