Question

2*(3*у+9)-5*у=3496 45*у+4*(25-7*у)=168

Answer 1

2*(3*у+9)-5*у=3496
6у+18-5у=3496
у=3496-18
у=3478

45*у+4*(25-7*у)=168
45у+100-28у=168
17у=168-100
17у=68
у=68/17
у=4

Answer 2

It looks like you have a system of two linear equations with one variable, which involves solving for the variable "у" in both equations. Let's solve this system step by step.

Equation 1: 2*(3у + 9) - 5у = 3496 Equation 2: 45у + 4(25 - 7*у) = 168

Let's start with Equation 1:

Simplify the equation: 6у + 18 - 5у = 3496 (6у - 5у) + 18 = 3496 у + 18 = 3496 у = 3496 - 18 у = 3478

Now, substitute the value of у into Equation 2:

Equation 2: 453478 + 4(25 - 7*3478) = 168

Simplify the equation: 156510 + 4*(25 - 24346) = 168 156510 + 4*(-24321) = 168 156510 - 97284 = 168 59226 = 168

The result is not consistent with the original equation, which means there might have been an error in the given equations or calculations. Please double-check the equations and values you provided.
