12w-24=12

解答

12 w - 24 = 12

w = 3

求解步骤

12 w - 24 = 12

将

24

到右边

12 w = 36

两边除以

12

w = 3

s im pl i f y \frac{( 8 c d ^{3} ) ( - 3 c ^{4} )}{6 c ^{2} d} - 9 c^{3} d^{2}

f a c t or x^{2} y + x^{4} y^{3}

9 = \frac{1}{2} (5 x + 6)

4 x^{2} + 15 x = 7 x - 3

f a c t or a^{2} - ab - 12 b^{2}
