There’s an app that can solve this easily called photo math it’s what I used But x= 3
<u>Use a more precise conversion factor if you need a more precise measurement. 1 g = 0.00220462262 lb. 1 lb = 453.592 g (if you want to convert pounds to grams, multiply number of pounds by 453.592)</u>
Answer: $5400
im assuming you want the total cost?
4000+1400=5400
1/5(2x - 10) + 4x = -3(1/5x + 4)
0.4x - 2 + 4x = -0.6x - 12
4.4x - 2 = -0.6x - 12
5x - 2 = -12
5x = -10
x = -2
