Question

The solution of equations system using the Substitution Method

Answer 1

Answer:

True

Step-by-step explanation:

$\begin{cases} y = 3x \\\\ 2y + 2x = 24\end{cases}$

Plugging y = 3x in the equation 2y + 2x = 24, we find:

2(3x) + 2x = 24

6x + 2x = 24

8x = 24

x= 24/8

x = 3

Plugging x = 3 in the equation y = 3x we have:

y = 3*3 = 9

(x, y) = (3, 9)
