Which of the following equations has a solution of x = 5 10x/2=1
2 (x – 3) + 8 = 6x – 18
2x – 5 + 3x = 8 + 14
O 4(1 - 2) + 3 = -2 (2 + 2) + 1

10x/2=1.

5x=1

5/5=1/5

X=1/5 (wrong)

2(x-3)+8=6x-18 (right answer)

2x-6+8=6x-18. you multiple 2 by x and 3

2x+2=6x-18 subtract 2x on both sides

-2x -2x

2=4x-18 Add 18 on both sides

+18. +18

20=4x. Divide by 4 on both sides

20/4 4/4

5=x (right answer)

Step-by-step explanation:

Look up for the steps

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
