solve the equation

Answer 1

this is an absolute value inequality btw

Does that help?

Answer 3

@tejadab268 step by step please !!!

thank you

Answer 4

@jhonyy9

(5)/(2)*a-4>=15

Multiply (5)/(2) by a to get (5a)/(2).
(5a)/(2)-4>=15

Since -4 does not contain the variable to solve for, move it to the right-hand side of the inequality by adding 4 to both sides.
(5a)/(2)>=4+15

Add 15 to 4 to get 19.
(5a)/(2)>=19

Multiply each term in the inequality by 2.
(5a)/(2)*2>=19*2

Simplify the left-hand side of the inequality by canceling the common factors.
5a>=19*2

Multiply 19 by 2 to get 38.
5a>=38

Divide each term in the inequality by 5.
(5a)/(5)>=(38)/(5)

Simplify the left-hand side of the inequality by canceling the common factors.
a>=(38)/(5)
