Question

1.) 0,5x + 0,15 =0
2.) 4y+15 =6y+17
3.) 3y-(5-y)=1
4.) 13-(5x+11)=6x
5.) 2 =(3x-5)-(7-4x)

Answer 1

0,5x+0,15=0
0,5x=-0,15
x=-0,3

4y+15=6y+17
4y-6y=17-15
-2y=2
y=-1

3y-(5-y)=1
3y-5+y=1
4y-5=1
4y=6
y=1,5

13-(5x+11)=6x
13-5x-11=6x
2-5x=6x
-5x-6x=-2
-11x=-2
x=2/11

2=(3x-5)-(7-4x)
2=3x-5-7+4x
2=7x-12
-7x=-12-2
-7x=-14
x=2
