Question

2)7-2x=4+x
3)5i-6=3-4i
4)9-3x=-5+4x
5)7x+10=6x-5
​

Answer 1

2) 7-2x = 4+x

-2x-x = 4-7

-3x = -3•(-1)

3x = 3

x = 3

3

x=1

3) 5i-6 = 3-4i

5i+4i = 3+6

9i = 9

i = 9

9

i=1

4) 9-3x = -5+4x

-3x-4x = -5-9

-7x = -14•(-1)

7x = 14

x = 14

7

x=2

5) 7x+10 = 6x-5

7x-6x = -5-10

1x = -15•(-1)

x=15
