solvefor b,a=3(b+c)

解答

求解

b, a = 3 (b + c)

b = \frac{a}{3} - c

求解步骤

a = 3 (b + c)

交换两边

3 (b + c) = a

两边除以

3

b + c = \frac{a}{3}

将

c

到右边

b = \frac{a}{3} - c

(d^{+} 2 d + 2) = x^{+} x + 1

so l v e f or x, 7 x + y = 58

a = (4 x - 1) (x + 3) - 4 x (x - 1) + 7 x

so l v e f or p, \frac{p}{q} = [(\frac{2}{3})]

so l v e f or x, x + y + 4 x + 4 y = 2
