Solving two linear equations with two unknowns 0.7X 1 +X 2 = 630 X 1 +(2/3)X 2 = 708 Step 1 : multiply first equation by 2/3 and rewrite, (1.4/3) X 1 +(2/3)X 2 = 420 X 1 +(2/3)X 2 = 708 Step 2: subtract first equation from second equation, (1-(1.4/3)) X 1 = 288 Step 3: divide by (1-(1.4/3)) = 0.5333, X 1 = 540.338

Unformatted text preview: Step 4: substitute the value of X 1 in the first equation, where 0.7 x 540.338 = 378.236, 378.236+ X 2 = 630 Therefore: X 2 = 630 – 378.236 = 251.764 Rounding to the closest integers we get (540, 252), which is identical to the solver’s solution....
