Determine Whether Each Set Is A Basis For R 3 Problems In Mathematics
Ex 21, 1 If (x/3 " 1, y –" 2/3) = (5/3 "," 1/3) , find the values of x and y (x/3 " 1, y –" 2/3) = (5/3 "," 1/3) Since the ordered pairs are equal, corresponding elements are equal Hence 𝐱/𝟑 1 = 𝟓/𝟑 x/3 = 5/3 – 1 x/3 = 2/3 x = 2 y – 𝟐/𝟑 = 𝟏/𝟑 y = 1/3 2/3When solving systems of equations in three variables, it is generally recommended to use the elimination method to eliminate a variable This will need to be repeated until all variables are determined Example Solve the following system x y z = 4 x − 2 y − z = 1 2x − y − 2 z = −1 First, let's eliminate x

X – 3y= 8 asked Dec 6 in Linear Equations by AhanaJain ( 341k points) pair of linear equations in two variablesAccording to the 7period for n^2 and n^31 (mod 7) LHS=RHS requires both to be 0 mod(7), so that for some n and k y^2=n*7^2 must equal k* 7^3 1 and therefore 7^2(n7k)=1 , impossible, since 7^2>1 I note the table format doesn't come out right you have to do it yourselvesFirst type the equation 2x3=15 Then type the @ symbol Then type x=6 Try it now 2x3=15 @ x=6 Clickable Demo Try entering 2x3=15 @ x=6 into the text box After you enter the expression, Algebra Calculator will plug x=6 in for the equation 2x3=15 2(6)3 = 15 The calculator prints "True" to let you know that the answer is right More Examples
