The value of x and y is 5 , 7
<h3>What is an Equation ?</h3>
An expression consists of variables , constants and mathematical operators , when equated by any other algebraic expression or a constant it becomes an equation.
The equation given in the question is
(x + 1)/2 -(y+4)/11 = 2
(x+3) /2 + (2y+3)/17 = 5
It has to be solved for x and y ,
The simplification of the equation has to be done
and the equation is
11x-2y = 41 -----------1
and
17x +4y = 113 -------------------2
to find the solution elimination method will be followed as
Multiplying equation 1 by 2 and adding the both equations
39x = 195
x = 5
Substituting this value in equation 1
55 -2y = 41
y = 7
The value of x and y is 5 , 7

Step-by-step explanation:
<u>Step 1: Define Equation</u>
17 - (3x + 5) = 3x - 6
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute negative: 17 - 3x - 5 = 3x - 6
- Add 3x on both sides: 17 - 5 = 6x - 6
- Combine like terms: 12 = 6x - 6
- Isolate <em>x</em> term: 18 = 6x
- Isolate <em>x</em>: 3 = x
- Rewrite: x = 3
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 17 - (3(3) + 5) = 3(3) - 6
- Multiply: 17 - (9 + 5) = 9 - 6
- Add: 17 - 14 = 9 - 6
- Subtract: 3 = 3
Here we see that 3 does indeed equal 3.
∴ x = 3 is the solution to the equation.
