solve the system by substitution.

$y = 5x$
$y = 9x + 4$

answer attempt 1 out of 2

Explanation:

Step1: Substitute $y=5x$ into second equation

$5x = 9x + 4$

Step2: Isolate $x$ terms

$5x - 9x = 4$
$-4x = 4$

Step3: Solve for $x$

$x = \frac{4}{-4} = -1$

Step4: Substitute $x=-1$ into $y=5x$

$y = 5\times(-1) = -5$

Answer:

$(-1, -5)$
