4(x+3)=24

4(3x)=24

12x=24

12x/12= 24/12

X=2

5(x+2)=45

5x+10=45

15x=45

15x/15=45/15

x=3

5+4x=13

5+4x-4x=13-4x

5=9x

5/9=9x/9

5/9= x

56=8(x+3)

56=8x+24

56-24=8x+24-24

32=8x

32/32=8x/32

x=8/32

x=1/4

S/6+3=11

6(s/6)+ 3=6(11)

S+3=66

S+3-3=66-3

s=63

And can you tell me how to do:

2(d+4)=10?

I'm kinda confused

**Bosnian**, Wednesday, April 18, 2012 at 1:48am4 ( x + 3 ) = 24

4 * x + 4 * 3 = 24

4 x + 12 = 24

4 x = 24 - 12

4 x = 12 Divide both sides by 4

x = 12 / 4

x = 3

5 ( x + 2 ) = 45

5 * x + 5 * 2 = 45

5 x + 10 = 45

5 x = 45 - 10

5 x = 35 Divide both sides by 5

x = 35 / 5

x = 7

5 + 4 x = 13

4 x = 13 - 5

4 x = 8 Divide both sides by 4

x = 8 / 4

x = 2

56 = 8 ( x + 3 )

56 = 8 * x + 8 * 3

56 = 8 x + 24

56 - 24 = 8 x

32 = 8 x Divide both sides bv 8

32 / 8 = x

4 = x

x = 4

2 ( d + 4 ) = 10

2 * d + 2 * 4 = 10

2 d + 8 = 10

2 d = 10 - 8

2 d = 2 Divide both sides by 2

d = 2 / 2

d = 1

s / 6 + 3 = 11

s / 6 = 11 - 3

s / 6 = 8 Multiply both sides by 6

s = 6 * 8

s = 48
