一元一次方程形式多样,解法较多.同学们在解一元一次方程时,一定不要固化思维,而要学会用辩证的眼光看解一元一次方程.一、乘或除以小数1.除以小数.例1解方程(0.6x)/(0.3)+(0.8)/(0.05)-(0.4-x)/(0.1)=0.鼢每个分数中分子部分的小数与分母部分的小数均成整数倍关系,所以将分子除以分母,使原方程得到化简.将分子除以分母,得2x+16-4+10x=0.移项、合并,得12x=-12.解得x=-1. A one-time equation in various forms, many solutions.University students in the solution of a dollar equation, we must not solidify thinking, but to learn to use a dialectical look at the equation of the unitary one, multiplied or divided by the decimal 1. divided by the decimal. Example 1 Solve the equation (0.6x) / (0.3) + (0.8) / (0.05) - (0.4-x) / (0.1) = 0. 小 The fraction of the numerator in each fraction is an integer with the fraction of the denominator Therefore, divide the numerator by the denominator and simplify the original equation. Divide the numerator by the denominator and obtain 2x = 16-4 + 10x = 0. Move and combine to obtain 12x = -12. Solve x = - 1.
