Answer:
infinite solutions
Step-by-step explanation:
The coefficient of x in the first equation is 3 times the coefficient of x in the second equation. This means we can eliminate x by subtracting 3 times the second equation from the first:
(15x +12y) -3(5x +4y) = (18) -3(6)
0 = 0 . . . . . simplify (true for all values of x or y)
The system of equations has an infinite number of solutions.
Answer:
£2
Step-by-step explanation:
Let T represent T-shirt and H represent hat
5T + H = £27.00
2T + H = £12.00 Subtract two equation
5T + H - 2T - H = £27 - £12 ➡ 3T = £15 and T = £5 this is the cost for a t-shirt
If a t-shirt costs £5 and 2 t-shirt + a hat costs £12 then a hat costs £2
