Answer: -2x - 10
Steps: -2(x+5)
Apply the distributive law [ a(b + c) = ab + ac ]:
a = -2, b = x, c = 5
-2x + (-2) × 5
Apply minus/plus rules: -2x - 2 × 5
Multiply the numbers: 2 × 5 = 10
-2x - 10

Step-by-step explanation:
let 1 meter of sulu = s, lusia has m dollar

5s = 7s - 1 - 5
2s = 6
s = 3
m = 7s - 1 = 21 - 1 = 20
