Question

-t+2=4+5t
2w+3=4w-5
3x-1=5x
y-3=9-y
0,5z+6=z-1

Answer 1

-t+2=4+5t
2-4=6t
-2=6t
t=-⅓

2w+3=4w-5
3=2w-5
8=2w
w=4

3x-1=5x
-1=2x
x=-½

y-3=9-y
y=12-y
2y=12
y=6

0,5z+6=z-1
6=0,5z-1
7=0,5z
z=14

Answer 2

A) -t+2=4+5t
-t=4+5t-2
-t-5t=4-2
-6t=2
t=- 1/3
---------------
b) 2w+3=4w-5
2w-4w=-5-3
-2w=-8
w=4
----------------
c)3x-1=5x
3x-5x=1
-2x=1
x=- 1/2
----------------
d) y-3=9-y
y+y=9+3
2y=12
y=6
----------------
e)0,5z+6=z-1
0,5 z - z = -1-6
-0,5z = -7
z=14
