Answer:
x = 17/4 = 4.25
Step-by-step explanation:
We assume your multiplication symbol (×) is intended to be a variable (x).
Simplifying, we have ...
17 -10x +45 = 6x -10 +4
68 = 16x
68/16 = x = 17/4 = 4.25

Check
17 -5(2(4.25) -9) = -(-6(4.25) +10) +4
17 -5(8.50 -9) = -(-25.5 +10) +4
17 -5(-0.5) = 15.5 +4
17 +2.5 = 19.5 . . . . . . true
