solvefor x,a(x-b)+bx+c=a+b

解答

求解

x, a (x - b) + b x + c = a + b

解答

x = \frac{a + b - c + ab}{a + b}; a \neq = - b

求解步骤

a (x - b) + b x + c = a + b

将

c

到右边

a (x - b) + b x = a + b - c

展开

a (x - b) + b x : x a - ab + x b

x a - ab + x b = a + b - c

将

ab

到右边

x a + x b = a + b - c + ab

分解

x a + x b : x (a + b)

x (a + b) = a + b - c + ab

两边除以

a + b; a \neq = - b

x = \frac{a + b - c + ab}{a + b}; a \neq = - b

-b/(0.2)-1.7=7.8

- \frac{b}{0.2} - 1.7 = 7.8

5 x - 6 = 18 - 3 x

7(3)x+1-5x+2=3x+4-5x+3

7 (3) x + 1 - 5 x + 2 = 3 x + 4 - 5 x + 3

2 - 3 x = - 9 - 4 x

2sqrt((1)^2-(1)+2)+C=3sqrt(2)

2 (1)^{2} - (1) + 2 + C = 32
