To solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the …

∵y³+3y-4=0 ==>y³-y²+y²-y+4y-4=0 (配方法)==>y²(y-1)+y(y-1)+4(y-1)=0==>(y-1)(y²+y+4)=0==>y-1=0 (∵y²+y+4>0)==>y=1∴原方程的解是y=1

2019年9月21日 · x^4／3^4＋y^4／3^4＝z^2／3^4， 则有（x／3）^4＋（y／3）^4 ＝（z／9）^2 则x，y，z不是最小正整数解，以上均为解释过程。 再由x^4＋y^4＝z^2可得x，y，z只能有两项为为奇数，一项为偶数（比较简单，可自己证明），所以分两种情况（以下奇，偶表示奇数和偶 …

Step 1: Lets plot both the equations on the graph. Step 2: Increase till these lines intersect each other. We get the intersection point as (3,-4) Since the lines are intersecting at (3, – 4), hence the solution of given equations is (3, – 4). Since the lines are intersecting only at one point, therefore the given lines will have only one solution.

Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Fields above the solid black line represent the numerator, while fields below represent the denominator. = ? Use this calculator if the numerators or denominators are very big integers.
