Solve the system by the substitution method,and identify the value of x of the solution.2x - 5y = 3y = -2x + 1 相关知识点: 试题来源: 解析 把Y=-2X+1代入2x-5y=32X-5(-2X+1)=32X+10X-5=3X=2/3把X=2/3代入y = -2x + 1得出Y= -1/3 ...
As an example, one can mention the discretized form (in time and space) of very general parabolic equations. A stable numerical scheme leads to such a system of linear equations. To solve these equations, they are generalized to matrices of the backward substitution method. (Auth.)...
Use the substitution method Solve the linear system: y = 3x + 2 Equation 2 Equation 1 x + 2y = 11 Solve for y. Equation 1 is already solved for y. SOLUTION STEP 1 EXAMPLE 1 Use the substitution method 7x + 4 = 11 Simplify. ...
whereμ>0is a scalar parameter. Rewrite this equation as a system of first-order ODEs by making the substitutiony′1=y2. The resulting system of first-order ODEs is y′1y′2=y2=μ(1−y21)y2−y1. The function filevdp1.mrepresents the van der Pol equation usingμ=1. The variab...
Use the substitution method to solve the system of equations. Choose the correct ord
Use the substitution or elimination method to solve each system of equations. State whether it is an inconsistent system or has infinitely many solutions. If a system has infinitely many solutions, write the solution set with y arbitrary.2x+y+z=3x+2y-z=33x-y+z=5 相关知识点: 试题来源:...
