Question

X - 8    3 .2 ------ - ------- 7          1.6

Answer 1

(х-8)/7=3,2/1,6
1,6(х-8)=7*3,2
1,6х-12,8=22,4
1,6х=22,4+12,8
1,6х=35,2
х=35,2:1,6
х=22

Answer 2

Х-8/7-2.0=0
х-8/7=2
х-8=7*2
х=14+8=22

Answer 3

To simplify the given expression, let's first find the common denominator for 3.2 and 1.6, which is 1.6.

Next, we can rewrite the expression as follows:

(X - 8) / 3.2 - 7 / 1.6

Now, let's simplify each fraction separately:

(X - 8) / 3.2 = (X - 8) / (3.2/1.6) = (X - 8) / 2

Similarly,

7 / 1.6 = 7 / (1.6/1.6) = 7 / 1 = 7

Now, we can rewrite the expression:

(X - 8) / 2 - 7

This cannot be simplified any further unless you provide the value of X. If you provide the value of X, we can substitute it into the expression to find the final result.
