5x + 2(x + 4) = 64
how do I solve for something like this and figure out what x equals?​

There are many way to solve this problem. But I'm using one X = 5 and X = 8.

Step-by-step explanation:

5 x 10 = 50

50 + 2 = 52

52 + 12 = 64

Heads up

4 + 8 = 12

x=8

Step-by-step explanation:

first you have to multiply 2 and x and then 2 and 4. You should get 2x + 8. then you should add comon numwrals which would be 5x and 2x to get 7x. your equation should now be 7x + 8= 64. then subtract 8 from 64 to get 56. it should now be 7x = 56. devide 56 by 7 and 7x by 7. your answer is x=8

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
