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

And can you tell me how to do:
2(d+4)=10?
I'm kinda confused

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
