Because all the digits are the same, each digit is worth 10x the one to its right and 1/10 of the one to its left.
This is because we count in base 10. This is also why we can expand this number to become
9*10^6+ 9*10^5+ 9*10^4+ 9*10^3+ 9*10^2+ 9*10^1 +9*10^0.
Answer:
ABC = 27
DBC = 56
Step-by-step explanation:
ABC + CBD = ABD
x+10 + 4x-12 = 83
Combine like terms
5x -2 = 83
Add 2 to each side
5x-2+2 = 83+2
5x = 85
Divide each side by 5
5x/5 = 85/5
x =17
ABC = x+10 = 17+10 = 27
DBC = 4x-12 = 4*17 -12 = 68-12 = 56
since y = both rewrite as
32x+6 = 14x-2 and solve for x
32x +6 = 14x-2
add 2 to both sides:
32x +8 = 14x
subtract 32x from both sides:
8 = -18x
divide both sides by -18
x = 8/-18 which reduces to -4/9
now use that for x and solve for Y
32(-4/9) +6 = -74/9
ordered pair:
(-4/9, -74/9)
