Let n be a number
2n - 3 = 55
Add 3 to both sides
2n + (-3 + 3) = 55 + 3
2n = 58
Divide 2 to both sides
2n/2 = 58/2
n = 29
Hope this helped!

Answer:
1.9
Step-by-step explanation:
2x+7=10.8
2x=3.8
x=1.9
1.9x2=3.8+7=10.8
2.5 x 10⁻²
Move the decimal two places to the right and multiply by 10 to the power of -2
75
Reduction of 12
3 x 4 = 12
Increase of 10
5 x 2 = 10
75 - 12 = 63
63 + 10 = 73
Change = 2 inches (75 - 73)
