Question

957-(t+336)=428 325-(a-617)=219 468-(259-c)=382 найти значение a,t,c

Answer 1

957 - (t + 336) = 428

t + 336 = 957 - 428

t + 336 = 529

t = 529 - 336

t = 193

- - - - - - - - - - - -

325 - (а - 617) = 219

а - 617 = 325 - 219

а - 617 = 106

а = 106 + 617

а = 723

- - - - - - - - - - - -

468 - (259 - с) = 382

259 - с = 468 - 382

259 - с = 86

с = 259 - 86

с = 173

Answer 2

To find the values of a, t, and c, we can solve each equation one by one. Let's start with the first equation:

1. 957 - (t + 336) = 428

Step 1: Remove the parentheses using the distributive property. 957 - t - 336 = 428

Step 2: Combine like terms. 621 - t = 428

Step 3: Isolate t on one side by subtracting 621 from both sides. 621 - 621 - t = 428 - 621 -t = -193

Step 4: Solve for t by multiplying both sides by -1. t = 193

Now, let's move on to the second equation:

2. 325 - (a - 617) = 219

Step 1: Remove the parentheses using the distributive property. 325 - a + 617 = 219

Step 2: Combine like terms. 942 - a = 219

Step 3: Isolate a on one side by subtracting 942 from both sides. 942 - 942 - a = 219 - 942 -a = -723

Step 4: Solve for a by multiplying both sides by -1. a = 723

Finally, let's solve the third equation:

3. 468 - (259 - c) = 382

Step 1: Remove the parentheses using the distributive property. 468 - 259 + c = 382

Step 2: Combine like terms. 209 + c = 382

Step 3: Isolate c on one side by subtracting 209 from both sides. 209 + c - 209 = 382 - 209 c = 173

So, the values of a, t, and c are:

a = 723 t = 193 c = 173
