Answer:
20x-8 =18x+6
20x-18x=6+8
2x=14
x=7
Step-by-step explanation:
expand the brackets
group the numbers into light terms
reduce the answers into light terms n then you get yr x
Answer: 600 m/s^2
Use the first kinematic equation
2/7(x-2)=4x
(2×x-2×2)/7 = 4x
(2x-4)/7 = 4x
2x-4×(1) = 4x × 7 ( Cross multiply)
2x-4 = 28
2x = 32
2x÷2 = 32÷2
x=16
2nd or 3rd one
I say that because the equation is over -3 for both.
Hope this helps you! :)
