Equações coloque a resposta com as conta de cada uma
5X+7=4X+10
4X-10=2X+2
4X-7=8X-2
2X+1=4X-7
5X-3+X=2X+9
16X-1=12X+3
3X-2=4X+9

Answer 1

Resposta:

5X+7=4X+10

5x-4x= 10-7

x=3

4X-10=2X+2

4x-2x= 2+10

2x=12

x=12/2

x=6

4X-7=8X-2

4x-8x= -2 +7

-4x= 5

x= 5/-4

2X+1=4X-7

2x-4x= -7-1

-2x= -8

x= -8/-2 (-1)

x=4

5X-3+X=2X+9

5x+x-2x= 9+3

4x=12

x=12/4

x=3

16X-1=12X+3

16x-12x= 3+1

4x=4

x=4/4

X=1

3X-2=4X+9

3x-4x=9+2

-x=11
