Question

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

Answer 1

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
