Answer:
x = - 
Step-by-step explanation:
Given
- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides
- 8x - 6 = 3x + 3 ( subtract 3x from both sides )
- 11x - 6 = 3 ( add 6 to both sides )
- 11x = 9 ( divide both sides by - 11 )
x = - 
Initial cost of the jet ski = $925
Percentage of depreciation per year = 15%
Number of years after which the cost of the jetski has to be determined = 7
Then
Depreciated Value = Initial cost( 1 - percentage of depreciation) ^number of years
= 925( 1 - 15%)^7
= 925( 1 - 15/100)^7
= 925(1 - 0.15)^7
= 925(0.85)^7
= 925 *(0.85)^7
= 925 * 0.3206
= 296.53 dollars
So the depreciated cost of the jet ski after 7 years will be $296.53

Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
4*(-2*x+7)-(24)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
4 • (7 - 2x) - 24 = 0
Step 2 :
Step 3 :
Pulling out like terms :
3.1 Pull out like factors :
4 - 8x = -4 • (2x - 1)
Equation at the end of step 3 :
-4 • (2x - 1) = 0
Step 4 :
Equations which are never true :
4.1 Solve : -4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
4.2 Solve : 2x-1 = 0
Add 1 to both sides of the equation :
2x = 1
Divide both sides of the equation by 2:
x = 1/2
