0.5 (x+1.6) + 1.4 (3x+2.4) = 9.8

1.2

Step-by-step explanation:

0.5 (x + 1.6) + 1.4 (3x + 2.4) = 9.8

0.5 (1.6 + x) + 1.4 (3x + 2.4) = 9.8

(1.6 * 0.5 + x * 0.5) + 1.4 (3x + 2.4) = 9.8

0.8 + 0.5x + 1.4 (2.4 + 3x) = 9.8

0.8 + 0.5x + (2.4 * 1.4 + 3x * 1.4) = 9.8

0.8 + 0.5x + (3.36 + 4.2x) = 9.8

0.8 + 3.36 + 0.5x + 4.2x = 9.8

0.8 + 3.36 = 4.16

4.16 + 0.5x + 4.2x = 9.8

0.5x + 4.2x = 4.7x

4.16 + 4.7x = 9.8

4.16 + 4.7x = 9.8.

Add '-4.16' to each side of the equation.

4.16 + - 4.16 + 4.7x = 9.8 + - 4.16

4.16 + - 4.16 = 0.00

0.00 + 4.7x = 9.8 + - 4.16

4.7x = 9.8 + - 4.16

9.8 + - 4.16 = 5.64

4.7x = 5.64

Divide each side by '4.7'.

x = 1.2

Therefore the answer

x = 1.2
