Question

Is the equation a true statement when x = 4? In other words, is 4 a solution to theequation?-2x – 3 + 5x = 12A. Yes, 4 is a solution.B. No, 4 is not a solution.

Answer 1

Solution

To find out whether the statement is true,

we need to substitute x = 4 in the expression and see whether the LHS = RHS

$-2(4)-3+5(4)=-8-3+20=9\ne12$

We can conclude that 4 is not a solution.

B. No, 4 is not a solution
