1. Wykonaj wskazane przekształcenia
a. 2t + 4 = t-3 | -4
..... = .....
b. 1-3t = 3 -4t | +4t
..... = .....
c. x = 1/5x - 3 |-1/5x
.....=.....
d.1/4y = 3+ y | -y
....=.....
e. x+1/4 = 2x+1/2 | x4
.....=......
f, 3(x - 8) = 6x - 9 | ;3

1. Wykonaj wskazane przekształcenia
a. 2t + 4 = t-3 | -4
2t = t-7
b. 1-3t = 3 -4t | +4t
1+t = 3
c. x = 1/5x - 3 |-1/5x
4/5x=-3
d.1/4y = 3+ y | -y
-3/4y=3
e. x+1/4 = 2x+1/2 | x4
4x+1=8x+2.
f, 3(x - 8) = 6x - 9 | ;3
x-8=2x-3
2. Zapisz jakie działania wykonano po obu stronach równania.
a. 5x - 1 = 1/2(3x - 8) | :1/2
10x - 2 = 3x-8 | -3x
7x - 2 = -8 |+2
7x = -6 |:7
x = -6/7
