Question

1) 9*(6x-13)=153 2)(46x-57):3=27 решите уравнения

Answer 1

9*(6х-13)=153
6х-13=153:9
6х-13=17
6х=17+13
6х=30
х=30:6
х=5

(46х-57):3=27
46х-57=27*3
46х-57=81
46х=81+57
46х=138
х=138:46
х=3

Answer 2

1) 9*(6x-13) = 153 First, distribute the 9 on the left side of the equation: 54x - 117 = 153 Add 117 to both sides: 54x = 270 Divide both sides by 54: x = 5

2) (46x-57)/3 = 27 First, multiply both sides by 3 to get rid of the fraction: 46x - 57 = 81 Add 57 to both sides: 46x = 138 Divide both sides by 46: x = 3

So the solutions to the equations are x = 5 and x = 3.
