WebThat would be translated into: ∑ x = 1 8 ∑ y = 1 9 − x 10 x + y. You could use the following code in Wolfram Alpha: sum (x=1 to 8) sum (y=1 to 9-x) 10^ (x+y) The result of this operation is 8 765 432 100. If the lower bounds would be 0 instead of 1 the rest would have to be recalculated: 0 <= x <= 9 0 <= y <= 9 - x. WebStep 1: Simplify the given equation by expanding the parenthesis if needed. Step 2: Solve any one of the equations for any one of the variables. You can use any variable based on the ease of calculation. Step 3: Substitute the obtained value of x or y in the other equation.
WebFor the cross-multiplication method for solving 2 variable equation, the formula used is: x / (b1 c2 − b2 c1) = y / (c1 a2 − c2 a1) = 1 / (b2 a1 − b1 a2) For example, consider the equations 2x + 3y = 9 ———– (i) And, x – y = 3 ———– (ii) Here, a 1 = 2, b 1 = 3, c 1 = -9 a 2 = 1, b 2 = -1, c 2 = -3 Now, solve using the aforementioned formula. WebTo solve or isolate a variable means to get the variable on one side of the equation by itself. Use inverse operations to move all the other variables or constants to the other side of the equation. In order to keep the equation …
