Answer:
x=-4.67
Step-by-step explanation:
add like terms 3-17
then take x=2x-14
add 2x to both sides
3x=-14
divide by 3 and you get your answer
x = 14
x = 2x + 3 - 17
x = 2x - 14 ( put together like terms )
x - 2x = -14 ( subtracted 2x from the right side and placed it on the left )
-x = -14 ( like terms )
x = 14 ( subtraction signs cancelled each other out )
it equals 6k but an equivalent expression could be 2k + 4k
2k + 4k = 4k + 2k
3/2 mph
=
cross-multiply: 8r = 12
r = 12/8 or 1.5 mph
