C because x represent the cost of books while 2 can be an additional price for the pens
Answer:
x=3
y=-1
Step-by-step explanation:
x=4+y
by substitution it in equation 1
weget
(4+y)+y=2
4+2y=2
y=-1
x=3
<span>The answer is:
T : (x, y) (x + 4, y + 3)
</span>T⁻¹<span>: (x, y) (x - 4, y - 3)
</span><span>The basic principle is to find the inverse function of F, such that T*</span>T⁻¹ = T⁻¹ * T = I.
