Hi,
*Note: when 'solving' for a variable, we must isolate the variable on one side of the equation
7 + 6/a =5
Multiplying each term on both sides of the equation by a so as all denominators = 1
7a + 6 = 5a
Performing operations necessary on both sides of the equation to isolate 'a'
7a + 6 = 5a subtracting 5a from both sides
2a + 6 = 0 subtracting 6 from both sides of equation
2a = -6 divding both sides by 2
a = -3
