Answer:
x = 6/5
Explanation:
Solve for x:
0 = (-5 (x - 6/5))/4
Put each term in x - 6/5 over the common denominator 5: x - 6/5 = (5 x)/5 - 6/5:
0 = (-5)/4 (5 x)/5 - 6/5
(5 x)/5 - 6/5 = (5 x - 6)/5:
0 = (-5)/4 (5 x - 6)/5
(-5)/5 = (5 (-1))/5 = -1:
0 = (-1 (5 x - 6))/4
0 = (-(5 x - 6))/4 is equivalent to (-(5 x - 6))/4 = 0:
(-(5 x - 6))/4 = 0
Multiply both sides of (-(5 x - 6))/4 = 0 by -4:
(-4 (-(5 x - 6)))/4 = -4×0
(-4)/4 = (4 (-1))/4 = -1:
--1 (5 x - 6) = -4×0
(-1)^2 = 1:
5 x - 6 = -4×0
0 (-4) = 0:
5 x - 6 = 0
Add 6 to both sides:
5 x + (6 - 6) = 6
6 - 6 = 0:
5 x = 6
Divide both sides of 5 x = 6 by 5:
(5 x)/5 = 6/5
5/5 = 1:
Answer: x = 6/5
