Answer 1

Answer:

a.1

b.-9/5

c.3

d.no

e.0.6

Answer 2

Step-by-step explanation:

1) 2x+1=0

2x=-1. x=-1/2

2) x+5=7 than 2x-3=?

x= 7-5

x=2 putting x in the equation

2×2-3=1

3)5x+5=-4

5x =-4-5

5x=-9

x=-9/5

4) 0.5y=1.5

y=1.5/0.5

y= 3

5) p=4 than 5(p+3)=7

5(4+3)=7

20+15=7

35=7

35-7=28.

6)x+2.4-2=3. than x is

x+2.4=3+2

x+2.4=5

x=5-2.4

x= 2.6

hope it helps you..
