Solve by Substitution y=8x-4 x=4

$y = 8 x - 4$ $x = 4$

Step 1

Replace all occurrences of $x$ with $4$ in each equation.

Replace all occurrences of $x$ in $y = 8 x - 4$ with $4$ .

$y = 8 (4) - 4$

$x = 4$

Simplify the right side.

Simplify $8 (4) - 4$ .

Multiply $8$ by $4$ .

$y = 32 - 4$

$x = 4$

Subtract $4$ from $32$ .

$y = 28$

$x = 4$

$y = 28$

$x = 4$

$y = 28$

$x = 4$

$y = 28$

$x = 4$

Step 2

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

$(4, 28)$

Step 3

The result can be shown in multiple forms.

Point Form:

$(4, 28)$

Equation Form:

$x = 4, y = 28$

Step 4
