-2
Because -2(10x+3) is (-20x-6) when you distribute
The solution to the system of equation are (0, -2) and (1, 0)
<h3>Solution to system of equations</h3>
System of equations are equations that has unknown and more than 1 equations.
Given the system of equations
y = x^2 + x – 2
y = 2x – 2
Equate both expressions
x^2 + x -2 = 2x - 2
x^2 - x = 0
x(x-1) = 0
x = 0 and x - 1 = 0
x = 0 and 1
If x = 0
y = 0 - 2 = -2
If x = 1
y = 2 - 2 = 0
Hence the solution to the system of equation are (0, -2) and (1, 0)

Ratio of men to women: 21:28, also simplified as 3:4
Ratio of women to the total number of people: 28:49 which is also 4:7
Answer:
Step-by-step explanation:
moments about the fulcrum should be equal
IF x is the distance of the fulcrum from the 90 lb child
90[x] = 60[12 - x]
90x = 720 - 60x
150x = 720
x = 4.8 ft
90(4.8) = 432 ft•lb
60(12 - 4.8) = 432 ft•lb
