On step 2 you already substituted for y, from there you can solve for x:
7x + 2(3 - 3x) = 1
Multiply 2 into (3 - 3x)
7x + 6 - 6x = 1
Combine like terms
x + 6 = 1
Subtract 6 on both sides
x = -5
19.5 meters you multiply 3 seconds by 6.5, there are 6.5 meters per second, thus implying each second is 6.5 meters. Equaling 19.5
Answer:
