Answer:
7x
Step-by-step explanation:
By combining like terms, which is 4x and 3x, we get 7x.
4x + 3x = 7x
The expression is not factorable with rational numbers...
4/5 (2x + 5) − 4 =1
4/5(2x +5) = 1 +4
4/5 (2x +5) = 5
2x + 5 = 5 / (4/5)
2x + 5 = 5 (5/4)
2x + 5 = 25/4
2x = 25/4 - 5
2x = 25/4 - 20/4
2x = 5/4
x = (5/4) / 2
x = (5/4) (1/2)
x = 5/8
x = 0.625
