solve by substitution: addition, subtraction or multiplication.

3X+Y-11 and -2X+Y=1

X=

Y=

From the 2nd:

y = 1 + 2x

typo in the first, once you fix it, replace y with (1+2x) and solve for x
Then sub that into 1+2x to get the y

let me know how you made out.

To solve this system of equations by substitution, we will solve one of the equations for one variable and substitute it into the other equation.

Let's solve the second equation for Y:

-2X + Y = 1

We can isolate Y by moving -2X to the other side:

Y = 2X + 1

Now that we have the expression for Y in terms of X, we can substitute it into the first equation:

3X + Y - 11 = 0

Substitute Y with 2X + 1:

3X + (2X + 1) - 11 = 0

Simplify the equation by combining like terms:

5X - 10 = 0

Add 10 to both sides of the equation:

5X = 10

Finally, divide both sides of the equation by 5 to solve for X:

X = 10/5 = 2

Now that we have X = 2, we can substitute this value back into Y = 2X + 1 to find Y:

Y = 2(2) + 1

Y = 4 + 1

Y = 5

Therefore, the solution to the system of equations is:

X = 2
Y = 5
