➷ x + y = 66
y - x = 22 (rearrange for y)
y = x - 22 (substitute this into the top equation)
x + (x - 22) = 66
2x - 22 = 66
Add 22 to both sides
2x = 88
x = 44
The two numbers are 44 and 22

Well 12 inches is a foot so 24inches is 2 feet so there is a hint so 90 divided by 12 and there is part of it
1 kg = 0.001 metric tons..so 14327 kg = (14327 * 0.001) = 14.327 metric tons
and if 1 metric tons saves 17 trees....then 14.327 tons saves : 14.327 * 17 = 243.559 saved trees...and since u cant have 0.559 trees, u would round to 243 trees
Answer:
y = 4
x = -1
Step-by-step explanation:
4x + 3y = 8`
-
`4x` `–` `3y =` `-16`
=
6y = 24
y = 4
4x = 8 - 3*4
4x = -4
x = -1
Answer:
Yes :)
