You dividing 10 blocks to 5 in each side
Since we have the 2.1 next to the parenthesis, we need to first distribute.
2.1 * x & 2.1 * 5
2.1x + 10.5
Then we take that and add the equals seven to the problem to move onto the next step.
2.1x + 10.5 = 7
We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.
2.1x + 10.5 = 7
- 10.5 -10.5
2.1x = -3.5
To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.
2.1x = -3.5
/2.1 /2.1
x = 1.66666666667
Hope this helped!

Answer: 30792.80
=====================================
Work Shown:
We deposit P = 23400 dollars for t = 7 years, which is compounded n = 1 times per year at an interest rate of r = 4% = 0.04 (we'll use the decimal form of the interest rate)
So this means...
A = P*(1+r/n)^(n*t)
A = 23400*(1+0.04/1)^(1*7)
A = 23400*(1+0.04)^(7)
A = 23400*(1.04)^(7)
A = 23400*1.31593177923584
A = 30792.8036341187
A = 30792.80
