包含變數 X 的方程式:X2 + 2X - 2,Y = X + 5,X = sin(M),X + 3 = B + C SOLVE求解 X。像 X2 + 2X - 2 這樣的表示式被視為 X2 + 2X - 2 = 0。 使用下列語法輸入方程式:{方程式},{求解的變數}SOLVE 可求得 Y 的解,例如以下列方式輸入方程式時:Y = X + 5, Y 重要! 如果某...
解出方程5x + 3 = 2x - 4的解。Solve the equation 5x + 3 = 2x - 4. 相关知识点: 试题来源: 解析x = -7/3首先,将方程中的变量项移动到左边,常数项移动到右边:5x + 3 = 2x - 4 两边减2x:5x - 2x + 3 = -4 → 3x + 3 = -4 两边...
y=3x2-4 (1) y=2x+3 121 0=(3x2-4)-(2x+3)(2)-(1) This equation simpoifes to 0=3x^2-2x-7 which dass not factorise, so we need to use the quadratic formula to find the two possible ualces of x. x=(-b±√(b^2-4ac))/(2a)=\frac(-(-2)±√((22)^2-48*(-7))...

3(x + 4) = 3x + 12 -2(2x - 6) = -4x + 12 合并得:3x + 12 - 4x + 12 = -x + 24 步骤②: 将整理后的方程变为: -x + 24 = 8 步骤③: 移项解方程: -x = 8 - 24 → -x = -16 → x = 16 验证:将x=16代入原方程,左边=3(20)-2(26)=60-52=8=右边,解正确。
将等式两边减去4: \[\frac{3}{2}x = 10 - 4 \implies \frac{3}{2}x = 6\] **步骤2:解出\(x\)** 两边同乘以倒数\(\frac{2}{3}\): \[x = 6 \times \frac{2}{3} = 4\] **验证答案** 将\(x = 4\)代入原方程: 左侧为\(\frac{3}{2} \times 4 + 4 = 6 + 4 = 10...
