3t + 4s = $83
4t + 1s = $50 (x 4)
16t + 4s = $200
3t + 4s = $83 (minus them£
13t = $117 (divide by 13)
t = $9
sub t into first equation.
3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14
t = $9
s = $14

6.) -8
Answer:
one solution
(second option listed)
Step-by-step explanation:
We can that these two lines, each representing one equation/function, only meet at one specific value.
In a system of equations, we are essentially looking for a solution that works for both equations.
So, if both lines share a point/value (meaning they intersect), that point is a solution to the system of equations.
Because these lines only overlap at one point, this system of equations has one solution.
