Question

Решите срочно пж!!!!!
A) 6(y-1)=9.4-1.7y b) 3(2.4-1.1m)=2.7m+3.2

Answer 1

А)  6y-6=9.4-1.7y
     6y+1.7y = 9.4+6
     7.7y=15.4
     y = 15.4/7.7
     y = 2

7.2-3.3m=2.7m+3.2
7.2-3.2 = 2.7m+3.3 m
4 = 6m
m = 4/6
m = 2/3

Answer 2

A)
6(y-1)=9.4-1.7y.
6у-6 = 9,4-1,7у,
6у+1,7у = 9,4+6,
7,7у = 15,4,
у = 2;
b)
3(2.4-1.1m)=2.7m+3.2,
7,2-3,3м = 2,7м+3,2,
-3,3м-2,7м = 3,2-7,2,
-6м = -4,
м = - 2/3
