Question

375-(×-218)=123 и ещё один (×+624)-276=357

Answer 1

375-(x-218)=123;

x-218=375-123;

x-218=252;

x=252+218;

x=470

(x+624)-276=357;

x+624=357+276;

x+624=633;

x=633-624;

x=9

Answer 2

375-(х-218)=123

х-218=375-123

х-218=252

х=252+218

х=470

_______________

(х+624)-276=357

х+624=357+276

х+624=633

х=633-624

х=9

Answer 3

It seems there is a problem with the notation you used for the multiplication sign (×). In mathematical expressions, the most common symbol for multiplication is "", or it can be implied when two values are written next to each other. For clarity, I'll rewrite the two equations using the "" symbol:

1. 375 - (x * 218) = 123
2. (x + 624) - 276 = 357

Let's solve these equations one by one:

1. 375 - (x * 218) = 123

To isolate "x," we need to move the constant term (375) to the other side of the equation and then divide both sides by 218:

375 - 123 = x * 218 252 = x * 218 x = 252 / 218 x ≈ 1.155

2. (x + 624) - 276 = 357

First, combine the terms on the left side of the equation:

x + 624 - 276 = 357

Now, isolate "x" by moving the constant terms (624 and 276) to the other side of the equation:

x = 357 + 276 - 624 x = 633 - 624 x ≈ 9

So, the solutions for the two equations are approximately:

1. x ≈ 1.155
2. x ≈ 9
