x+3+x+1=4(x+1)

解答

x + 3 + x + 1 = 4 (x + 1)

解答

x = 0

求解步骤

x + 3 + x + 1 = 4 (x + 1)

对同类项分组

x + x + 3 + 1 = 4 (x + 1)

同类项相加:

x + x = 2 x

2 x + 3 + 1 = 4 (x + 1)

数字相加:

3 + 1 = 4

2 x + 4 = 4 (x + 1)

展开

4 (x + 1) : 4 x + 4

2 x + 4 = 4 x + 4

将

4

到右边

2 x = 4 x

将

4 x

6 (5 - 8 v) + 12 = - 54

7 j = 8 j - 3

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

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

(3x-1)/7+(2x-1)/3 =x

\frac{3 x - 1}{7} + \frac{2 x - 1}{3} = x

(3x-7)^2-5(2x+1)(x-2)=-x^2-[-(3x+1)]

(3 x - 7)^{2} - 5 (2 x + 1) (x - 2) = - x^{2} - [- (3 x + 1)]
