Hi there!
We can solve this equation by using the systems of equations.
We can do this by subtracting like terms from both equations using substitution.
First, let's find the value of y:
6x + 3y = 21
3y = -6x + 21
y = -2x + 7
Then, we should plug it into one of the equations:
3x - 7y = 2
3x - 7(-2x + 7) = 2
3x + 14x - 49 = 2
17x = 51
x = 3
Now, we solve for y by plugging the value of x into the equation:
3x - 7y = 2
3(3) - 7y = 2
9 - 7y = 2
-7y = -7
7y = 7
y = 1
There's your answers.
Hope this helps!

Step-by-step explanation:
The distance travelled by an object is 50 m.
<h3>What is Distance?</h3>
The distance between two points is the length of the path connecting them.
Here, given equation of distance
S = 1/2 (u + v)t
Where s is the distance traveled by an object (in meters)
initial velocity u (in m/s)
final velocity v (in m/s).
t in seconds.
Now, given values are;
u = 8 m/s ; v = 12 m/s ; t = 5 sec.
S = 1/2 (8 + 12)5
S = 1/2 (20)5
S = 100/2
S = 50 m.
Thus, the distance travelled by an object is 50 m.
