0=(3R)/(1.1)+R/(1.1^2)+R/(1.1^3)-900

0 = \frac{3 R}{1.1} + \frac{R}{1. 1 ^{2}} + \frac{R}{1. 1 ^{3}} - 900

R = 209.05759 \dots

Solution steps

0 = \frac{3 R}{1.1} + \frac{R}{1. 1 ^{2}} + \frac{R}{1. 1 ^{3}} - 900

Switch sides

\frac{3 R}{1.1} + \frac{R}{1. 1 ^{2}} + \frac{R}{1. 1 ^{3}} - 900 = 0

1. 1^{2} = 1.21

\frac{3 R}{1.1} + \frac{R}{1.21} + \frac{R}{1. 1 ^{3}} - 900 = 0

1. 1^{3} = 1.331

\frac{3 R}{1.1} + \frac{R}{1.21} + \frac{R}{1.331} - 900 = 0

Expand

\frac{3 R}{1.1} + \frac{R}{1.21} + \frac{R}{1.331} - 900 : 4.30503 \dots R - 900

4.30503 \dots R - 900 = 0

Move

900

to the right side

4.30503 \dots R = 900

Divide both sides by

4.30503 \dots

R = 209.05759 \dots

4 x - 3 (1 - 3 x) = - 3

2 4^{2} + 3 2^{2} = 4 0^{2}

- m + 8 = m + 22

4 + 0.5 x = 16

x, x y + y - x = 7
