Question

1)х+(327-19)=531 2)у(452+128)=359

Answer 1

1)х+(327-19)=531
х+318=531
х=531-318
х=213
2)у(452+128)=359
у*580=359
у=359:580
у= примерно 0.6

Answer 2

To solve the given equations, we need to find the values of the variables "х" and "у". Let's solve them step by step:

1. х + (327 - 19) = 531

First, perform the operations inside the parentheses:

х + 308 = 531

Now, isolate the variable "х" by subtracting 308 from both sides:

х = 531 - 308

х = 223

So, the value of "х" is 223.

2. у(452 + 128) = 359

First, perform the operation inside the parentheses:

у(580) = 359

Now, to find the value of "у", divide both sides by 580:

у = 359 / 580

у ≈ 0.6186 (rounded to four decimal places)

So, the value of "у" is approximately 0.6186.
