Question

Responda A)5X+7=4X+10 B)4x-10=2x+2 C)4x-7=8x-2 D)2x+1=4x-7

Answer 1

a)
5x + 7 = 4x + 10 
5x - 4x = 10 - 7
x = 3
-------------------------------------
b)
4x - 10 = 2x + 2 
4x - 2x = 2 + 10
2x = 12
x = 12/2
x = 6
---------------------------------
c)
4x - 7 = 8x - 2 
- 7 + 2 = 8x - 4x
- 5 = 4x
4x = - 5
x = - 5/4
------------------------------
d)
2x + 1 = 4x - 7
1 + 7 = 4x - 2x
8 = 2x
2x = 8
x = 8/2
x = 4

Answer 2

A)5X+7=4X+10

5x - 4x = 10 - 7

x= 3

B)4x-10=2x+2

4x - 2x = 2 + 10

2x = 12

x= 12/2

x= 6

C)4x-7=8x-2

4x - 8x = - 2 + 7

- 4x = 5 ( - 1)

4x = - 5

x= - 5/4

D)2x+1=4x-7

2x - 4x = - 7 - 1

- 2x = - 8 ( - 1)

2x = 8

x= 8/2

x= 4
