solvefor x,5(1_{2}t)+2(3-x)=3(x+4)+14

解答

求解

x, 5 (1_{2} t) + 2 (3 - x) = 3 (x + 4) + 14

解答

x = \frac{20}{- 5} - \frac{5 \cdot 1 _{2} t}{- 5}

求解步骤

5 (1_{2} t) + 2 (3 - x) = 3 (x + 4) + 14

5 \cdot 1_{2} t + 2 (3 - x) = 3 (x + 4) + 14

乘开

2 (3 - x) : 6 - 2 x

5 \cdot 1_{2} t + 6 - 2 x = 3 (x + 4) + 14

展开

3 (x + 4) + 14 : 3 x + 26

5 \cdot 1_{2} t + 6 - 2 x = 3 x + 26

将

5 \cdot 1_{2} t

到右边

6 - 2 x = 3 x + 26 - 5 \cdot 1_{2} t

将

6

到右边

- 2 x = 3 x + 20 - 5 \cdot 1_{2} t

将

3 x

para o lado esquerdo

- 5 x = 20 - 5 \cdot 1_{2} t

两边除以

- 5

x = \frac{20}{- 5} - \frac{5 \cdot 1 _{2} t}{- 5}

solvefor y,tan(x)-2x^3*y=c

so l v e f or y, tan (x) - 2 x^{3} \cdot y = c

solvefor x,2x+3/y =5

so l v e f or x, 2 x + \frac{3}{y} = 5

solvefor x,-10*y-x=7

so l v e f or x, - 10 \cdot y - x = 7

solvefor x,4x-3y-5=0

so l v e f or x, 4 x - 3 y - 5 = 0

(0) r = 10
