Can you correct the errors?

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

  • Math -

    4 ( 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
