Question

6)60+13×=3×
7)5×-27=-4×
8)9×+5=4×
9)11×+17=10×+3
10)20×-5=10×+15​

Answer 1

60 + 13X = 3X
13X - 3X = - 60
10X = - 60
X = - 60 : 10
X = - 6


5X - 27 = - 4X
5X + 4X = 27
9X = 27
X = 27 : 9
X = 3


9X + 5 = 4X
9X - 4X = - 5
5X = - 5
X = 5 : ( - 5 )
X = - 1


11X + 17 = 10X + 3
11X - 10X = 3 - 17
X = - 14


20X - 5 = 10X + 15
20X - 10X = 15 + 5
10X = 20
X = 20 : 10
X = 2
