Subtract 8 from both sides
So you end up with x = -23
Without values for the other variables, I assume you're asking for a literal equation.
12y+d=-19y+t
31y+d=t
31y=-d+t
y=(-d+t)/31
Hi There!
-----------------------------------------
We Know:
$35 per person.
Guides Fee: 10 * 35 = 350
425 - 350 = $75 (guide fee)
-----------------------------------------
Part A:
The problem states to put c as cost and p as number of people:
c = 35p + 75
b = $75 (guide fee)
If you don't need the one above, this is just in slope intercept form.
y = 35x + 75
b = $75 (guide fee)
Answer: c = 35p + 75 or y = 35x + 75
-----------------------------------------
Part B:
How much would it cost for 15 people?
Lets use: c = 35p + b
Substitute p for 15 people and b as $75 for the guide fee: c = 35(15) + 75
Simplify: c = $600
Answer: The total cost for 15 people is $600.

Hope This Helps :)
Multiply each row in the first matrix by each column in the second matrix:
1*2 + 3*3 + 1*4 1*-2 + 3*5 + 1*1
-2*2 + 1*3 + 0*4 -2*-2 + 1.5 + 0*1
Simplify to get
[15 14
-1 9]
The third choice is the correct answer.
Step-by-step explanation:
x² + 4x + y² + 16y - 20 = 0
(x² + 4x + 4) + (y² + 16y + 64) - 4 - 64 - 20 = 0
(x + 2)² + (y + 8)² = 88.
