1. 10(n-2) = 5*26
First, distribute the 10 on the left side of the equation:
10n - 20 = 130
Next, isolate the variable, n, by adding 20 to both sides:
10n = 150
Finally, divide both sides by 10 to solve for n:
n = 15
2. 4S + 24 - S + 37 + S = 129
First, combine like terms on the left side of the equation:
4S - S + S + 24 + 37 = 129
4S + 24 + 37 = 129
4S + 61 = 129
Next, subtract 61 from both sides:
4S = 68
Finally, divide both sides by 4 to solve for S:
S = 17
Solve the equations. Show steps.
1.10(n-2)=5x26
2. 4S+24-S+37+S=129
