Answer:
x = 5.25
Explanation:
subtract 7/10 from both sides of the equation
-8/9x +7/10 - 7/10 = -119/30-7/10
-8/9x = -119-21/30
-8/9x = -140/30
the negative signs cancels out and the right hand side reduced to the lowest tern
8/9x = 14/3
multiply both sides by the reciprocal of 8/9 which is 9/8
9/8 * 8/9x = 14/3 * 9/8
x = 21/4
x = 5.25
