Question

$$x+3x+5,x+7=15$$

Solve for x, y

$y=37$

Solution Steps

Consider the first equation. Subtract $7$ from both sides.

$$x=15-7$$

Subtract $7$ from $15$ to get $8$.

$$x=8$$

Consider the second equation. Insert the known values of variables into the equation.

$$y=8+3\times 8+5$$

Multiply $3$ and $8$ to get $24$.

$$y=8+24+5$$

Add $8$ and $24$ to get $32$.

$$y=32+5$$

Add $32$ and $5$ to get $37$.

$$y=37$$

The system is now solved.

$$x=8$$ $$y=37$$
