(iv) The process is then repeated, i.e. the first term of the divisor, x, is divided into 3x, giving +3, which is placed above the dividend as shown. (v) Then 3 (x − 1) = 3x − 3, which is placed under the 3x − 3. The remainder, on subtraction, is zero, which completes the process. Thus, (2x2 + x − 3) ÷ (x − 1)= (2x+ 3).
WebSolve the system of linear equations by graphing, and they give us two equations here. 5x plus 3y is equal to 7, and 3x minus 2y is equal to 8.

Web3 & = y - 2x \end{align*} We have two independent equations to solve for two unknown variables. algebraically using substitution and elimination methods. We will also show that a system of simultaneous equations can be solved graphically. Solving by … WebEither add or subtract the two equations from each other to eliminate the letter \(y\). In this example the equations will need to be subtracted from each other as \(y - y = 0\) .
WebTo express y as the subject of a formula means to isolate y on one side of the equation. Explanation: A) y=4x+9y Subtracting 9y from both sides: y - 9y = 4x Simplifying: -8y = 4x y = 4 x − 8 = − 0.5 x y = -0.5x So the expression y as the subject of the formula in option A is y = -0.5x.

Rewriting the equation - -2y + 5x = 10 : equation 1 -3y + 4x = 15 : equation 2 Multiplying equation 1 with 4 and equation 2 with 5 -8y + 20x = 40 : equation 3 -15y + 20x = 75 : equation 4 Subtracting equation 3 form equation 4 to eliminate variable y -7y = 35 the world\u0027s religions bookWebof 8 and 24 are 1, 2, 4 and 8 since 1, 2, 4 and 8 are factors of both 8 and 24. The highest common factor (HCF) is the largest number that divides into two or more terms. Hence, the HCF of 8 and 24 is 8, as explained in Chapter 1. When two or more terms in an algebraic expression contain a common factor, then this factor can be shown outside of a bracket. safety boots centurionWebAlgebra. Solve by Substitution Calculator.
