Answer 1

1)15d=6,3

d=6,3/15

d=0,42

2)21x=17+1,9

21x=18,9

x=18,9/21

x=0,9

3)1,7x=94,2-88,42

1,7x=5,78

x=5.78/1.7

x=3.4

Answer 2

1) 9d+6d=6,15+015; 15d=6,3 d=0,42
2) 17x-x+5x=17+1,9; 21x=18,9; Х=0,9
3) 1,7x=94,2-88,42; 1,7x=5,78; Х=3,4
4) 16,4-14,78=5,4x; 1,62=5,4x; Х=0,3
5) 10,2x-7,4x=2-0,88; 2,8x=1,12; Х=0,4
6) 0,6y+0,18y=5,58+2,376; 0,24y=8,176; У=33,15

Answer 3

Решение уравнений:

1) 9d + 6b - 0.15 = 6.15

To find the value of 'd' and 'b', we can solve this equation simultaneously.

2) 17x - x + 5x - 1.9 = 17

Combine like terms to simplify the equation and solve for 'x'.

3) 1.7x + 88.42 = 94.2

Subtract 88.42 from both sides and then solve for 'x'.

4) 16.4 - 5.4x = 14.78

Subtract 16.4 from both sides and then solve for 'x'.

5) 10.2x - 7.4x + 0.88 = 2

Combine like terms and then solve for 'x'.

6) 0.6y + 0.18y - 2.376 = 5.58

Combine like terms and then solve for 'y'.

I will now solve each of the equations step by step.
