Answer:
16
Step-by-step explanation:
4x3=12 tins of white paint
12+4=16 total tins
The answer is D. 10x-2y-6
If x + 4y = 6 and you subst. -x+3 for y, you get x + 4(-x+3) = 6.
Then x - 4x + 12 = 6, or -3x = -6, or x = 2. Since y = -x+3, here y = -(2)+3 = 1.
Thus, the solution to this system of linear equations is (2,1).
