Question

-8,8-x=3,7 2)x-9,21=-4,3 3)x+17/18*5/9

Answer 1

$1)-8,8x=3,7 \\ x=- \frac{37}{88} \\ 2)x-9,21=-4,3 \\ x=-4,3+9,21 \\ x=4,91$

Answer 2

It looks like you've provided three equations. Let's solve each of them step by step:

1. -8 + 8 - x = 3.7 Combine the constants on the left side: 0 - x = 3.7 + 8 -x = 11.7 Multiply both sides by -1 to solve for x: x = -11.7

2. x - 9.21 = -4.3 Add 9.21 to both sides: x = -4.3 + 9.21 x = 4.91

3. x + (17/18) * (5/9) To simplify the expression inside the parentheses, multiply the fractions: x + (85/162) The equation is already simplified. There's nothing more we can do without additional information.

So, the solutions are:

1. x = -11.7
2. x = 4.91
3. x + (17/18) * (5/9) or x + (85/162)
