In the given system of equations, the value of x is 7.334 and the value of y is 7.714
<h3>Solving system of linear equations</h3>
From the question, we are to solve the given system of linear equations
The given system of linear equations is
3x + 7y = 76 ------------ (1)
9y + 5y = 108 ------------ (2)
From equation (2), solve for y
9y+ 5y = 108
14y = 108
y = 108/14
y = 7.714
Substitute the value of x into equation (1), to determine the value of x
3x + 7y = 76
3x + 7(7.714) = 76
3x + 53.998 = 76
Subtract 53.998 from both sides of the equation
3x + 53.998 - 53.998 = 76 - 53.998
3x = 22.002
Divide both sides of the equation by 3
3x/3 = 22.002/3
x = 7.334
Therefore,
x = 7.334 and y = 7.714

Hi there!
This is pretty easy if you remember PEMDAS.
P = Parenthesis, and that's all we have in our equation so we'll work out what's in the parenthesis first.
(3×8) = 24. Then we go to the outside of the parenthesis and multiply 24 by whatever is on the outside.
24×1 =, well, 24.
Now we can go to the other side.
(8×1) = 8
8×3 = 24
Wow! Wouldja look at that? We are left with
24 = 24
The correct answer is A) True.
Hope this helps! <3
