Question

1. $5y = 10$

$x - 3y = 4$

Explanation:

Step1: Solve for $y$

Divide both sides of $5y=10$ by 5.
$\frac{5y}{5}=\frac{10}{5}$
$y=2$

Step2: Substitute $y=2$ into $x-3y=4$

Replace $y$ with 2 and solve for $x$.
$x-3(2)=4$
$x-6=4$

Step3: Solve for $x$

Add 6 to both sides of the equation.
$x=4+6$
$x=10$

Answer:

$x=10$, $y=2$
