Question

4у+2у-у=207у+у-2у=24

Answer 1

4у+2у-у = 20             7у+у-2у = 24
5у = 20                     6у = 24
у = 20 :5                   у = 24 : 6
у = 4                        у = 4
4*4 + 2*4 - 4 = 20      7*4 + 4 - 2*4 = 24

Answer 2

5y=20
y=20/5
y=4

6y=24
y=24/6
y=4

Answer 3

To solve the given equations, let's simplify and combine like terms:

Equation 1: 4у + 2у - у = 207у Combining the terms on the left side, we have: 5у = 207у

Equation 2: у + у - 2у = 24 Combining the terms on the left side, we have: у - у = 24 0 = 24

At this point, we can see that Equation 2 is contradictory since 0 cannot be equal to 24. This indicates that there is no solution to the system of equations.
