The original United States colonies were primarily under English land claims, starting with the establishment of Jamestown in 1607. By the mid-eighteenth century, thirteen colonies had developed, all governed under British charters. Other European countries, such as France and Spain, also held territories, but England had the most significant influence.

Jawab:Penjelasan dengan langkah-langkah:The solution to the system of linear equations 2p + q + 2r = 2, p + 2q + r = 4, and p + q + 2r = 3 is p = 1, q = 2, and r = -1. Here's how to solve it:1. Elimination Method:Step 1: Subtract the third equation (p + q + 2r = 3) from the first equation (2p + q + 2r = 2) to eliminate 'q' and 'r':(2p + q + 2r) - (p + q + 2r) = 2 - 3This simplifies to: p = -1Step 2: Substitute p = -1 into the second equation (p + 2q + r = 4) and the third equation (p + q + 2r = 3):-1 + 2q + r = 4 => 2q + r = 5-1 + q + 2r = 3 => q + 2r = 4Step 3: Solve the system of two equations with two variables (2q + r = 5 and q + 2r = 4):From the second equation, we get: q = 4 - 2rSubstitute this value of 'q' into the first equation: 2(4 - 2r) + r = 5Simplify and solve for 'r': 8 - 4r + r = 5 => -3r = -3 => r = 1Substitute the value of 'r' back into the equation q = 4 - 2r: q = 4 - 2(1) => q = 22. Solution:Therefore, the solution to the system of equations is p = -1, q = 2, and r = 1. 3. Verification (Optional):Substitute the values of p, q, and r into all three original equations to verify the solution:2(-1) + 2 + 2(1) = -2 + 2 + 2 = 2 (True)-1 + 2(2) + 1 = -1 + 4 + 1 = 4 (True)-1 + 2 + 2(1) = -1 + 2 + 2 = 3 (True)
