Question

25-3x=9-5x3+11y=203+1​

Answer 1

1) 25-3х=9-5х
-3х+5х=9-25
2х = -16
х=-16/2
х=-8

2) 3+11у=203+1
11у=204-3
11у=201
у=201/11
у= 18×(3/11) или ≈18,27

Answer 2

It looks like you have two equations here:

1. 25 - 3x = 9 - 5x
2. 3 + 11y = 203 + 1

However, the second equation seems to be missing an operator between "5x" and "3". Could you please clarify the second equation or provide the missing operator?

Assuming the second equation is supposed to be 5x * 3, the equations become:

1. 25 - 3x = 9 - 5x
2. 3 + 11y = 203 + 5x * 3

Now, let's solve for the variables x and y.

1. Solve for x: First, we'll simplify the equations: 25 - 3x = 9 - 5x Combine the x terms on one side: 25 - 9 = -3x + 5x 16 = 2x

Now, divide both sides by 2 to isolate x: x = 16 / 2 x = 8

2. Solve for y: Substitute the value of x (which we found to be 8) into the second equation: 3 + 11y = 203 + 5 * 3 3 + 11y = 203 + 15

Next, isolate y by moving the constant term to the other side: 11y = 203 + 15 - 3 11y = 215

Finally, divide both sides by 11 to find the value of y: y = 215 / 11 y ≈ 19.55 (rounded to two decimal places)

So, the solutions to the system of equations are: x = 8 y ≈ 19.55
