Rozwiąż równiania:
a 5y=13
b 1/7x=-2
c -7b=7/8
d 7a+7=35
e 2-x=5-2x
f 69-x=x+96
g 1/2c+5+c+8
Daję naj!
d.
7a+7=35
7a=28
a=4
tylko to wiedziałam
a) 5y = 13 / :5
y =2 i 3/5
b) 1/7x = -2 / *7
x = -14
c) -7b = 7/8 / *8
-56b = 7 / : -56
b = 7/56
b = 1/8
d) 7a+7 = 35
7a = 35 - 7
7a = 28 / :7
a = 4
e) 2 - x = 5 - 2x
-x + 2x = 5 - 2
x = 3
f) 69 - x = x + 96
x+x = 69 - 96
2x = - 27 / :2
x = -13 i 1/2
g) 1/2c + 5 = c+8
1/2c = - 3 / *2
c = - 6
