Examples: 1+2 , 1/3+1/4 , 2^3 * 2^2 (x+1) (x+2) (Simplify Example), 2x^2+2y @ x=5, y=3 (Evaluate Example) y=x^2+1 (Graph Example), 4x+2=2 (x+6) (Solve Example) Algebra Calculator is a calculator that gives step-by-step help on algebra problems. No connect the points and extend each end of the line to give you the graph of the line. Solve the system of inequalities graphically: 2x+y≥ 4,x+y≤3,2x−3y≤ 6 Medium Solution Verified by Toppr 2x+y>4 for all set of points which lies above the line 2x+y=4 x+y<3 for all set of points which lies below the line x+y=3 solution is shaded part. Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step. 00000 Rearrange: Rearrange the equation by subtracting. 00000 Rearrange: Rearrange the equation by subtracting what is to the 2x+y = 6 http://www. 4x=8 This is because when you add the two expression together 2x+2x=4x the y values cancel and -4+-4=-8 4x-8=0 is equivalent to 4x=8.
