Solve by Substitution x=11 -4x+y=-23

$x = 11$ $- 4 x + y = - 23$

Step 1

Replace all occurrences of $x$ with $11$ in each equation.

Replace all occurrences of $x$ in $- 4 x + y = - 23$ with $11$ .

$- 4 \cdot 11 + y = - 23$

$x = 11$

Simplify the left side.

Multiply $- 4$ by $11$ .

$- 44 + y = - 23$

$x = 11$

$- 44 + y = - 23$

$x = 11$

$- 44 + y = - 23$

$x = 11$

Step 2

Move all terms not containing $y$ to the right side of the equation.

Add $44$ to both sides of the equation.

$y = - 23 + 44$

$x = 11$

Add $- 23$ and $44$ .

$y = 21$

$x = 11$

$y = 21$

$x = 11$

Step 3

Solve the system of equations $y = 21 x = 11$ .

$y = 21 x = 11$

Step 4

The solution to the system is the complete set of ordered pairs that are valid solutions.

$(11, 21)$

Step 5

The result can be shown in multiple forms.

Point Form:

$(11, 21)$

Equation Form:

$x = 11, y = 21$
