Answer
solution
Work Step by Step
5a-4 = 2a+5;3
To check whether 3 is the solution of the given expression, substitute 3 for a.
5*3 - 4 = 2*3 + 5 (multiply 5*3 and 2*3)
15 -4 =6 +5(add 6+5)
15 -4 = 11(subtract 15 -4)
11 = 11
The statement is true, because the values on both sides of the equation are same. Therefore, the number 3 is the solution of the equation.
