solve the equation and check

1.9(5-x)=1.7(3-x)

1.9(5-x)=1.7(3-x)

9.5 - 9.5x = 5.1 - 1.7x
9.5 - 5.1 = 9.5x - 1.7x
4.4 = 7.8x
4.4/7.8 = x
? = x

what does then question mark me there is no solution

I expect you to divide 4.4 by 7.8 to get the answer.

what does the question mark mean

x=22/39

4.4 / 7.8 = 0.564102564

To solve the equation 1.9(5-x) = 1.7(3-x), we will follow the steps below:

Step 1: Expand the expression on both sides of the equation:
1.9 * 5 - 1.9 * x = 1.7 * 3 - 1.7 * x

Step 2: Simplify each side by performing the multiplication:
9.5 - 1.9x = 5.1 - 1.7x

Step 3: Move all the terms containing "x" to one side of the equation, and the constants to the other side:
-1.9x + 1.7x = 5.1 - 9.5

Step 4: Combine like terms:
-0.2x = -4.4

Step 5: Divide both sides of the equation by -0.2 to solve for "x":
x = (-4.4) / (-0.2)
x = 22

To check if the solution is correct, substitute the value of "x" back into the original equation:
1.9(5-x) = 1.7(3-x)

Substituting x = 22:
1.9(5-22) = 1.7(3-22)
1.9(-17) = 1.7(-19)
-32.3 = -32.3

Both sides of the equation are equal, so the solution x = 22 is correct.
