10t = 6t + 24 Subtract 6t from both sides to get the t's on one side.
4t = 24 Divide both sides by 4 to get t completely alone.
t = 6

Change 1/3 to 2/6 in order to have a common denominator.
Then add the numerators (2 and 5) and keep the denominator.
1/3 + 5/6 = 2/6 + 5/6
5 + 2 = 7
7/6
1/3 + 5/6 = 1 1/6 or 7/6

The value of y for the given expression will be -1.
What is an expression?
Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication and division.
Solve the system by substitution.
x = 2y + 3
4x-5y = 9
Substituting the value of x in equation no. 2, we have,
4(2y+3) - 5y = 9
8y + 12 - 5y = 9
3y + 12 = 9
3y = 9-12 = -3
The value of y is calculated as,
3y = -3
y = -3/3 = -1
y = -1
To know more about an expression follow

x = 2y + 3
4x-5y = 9
Substituting the value of x in equation no. 2 , we have,
4(2y+3) - 5y = 9
8y + 12 - 5y = 9
3y + 12 = 9
3y = 9-12 = -3
thus, 3y = -3
thus, y = -3/3 = -1
thus, y = -1

So now we have -18-6x-2x=14.
Simplify that to -18-8x=14.
Add 18 on both sides.
Now we have -8x=14+18.
-8x=32
Divide by -8 on both sides.
We get x=-4.

March . . . . 4 times as much = 4 (57.85) = $231.40
Deposit 78.45 more . . . ($231.40 + 78.45) = $309.85 .
Notice that "interest" is never mentioned anywhere in this problem.
In other words, it doesn't matter whether Julie's savings account is
in a bucket in the basement, a mayonnaise jar on the porch, under
her mattress, or in a bank that pays no interest.
Without interest, $309.85 is what she does have in November, which
is about right for savings accounts in banks these days.
What her balance should be in November is an entirely different subject.
