Answer (3)
8 x − 19 = − 4 − 7 x 8 x + 7 x − 19 + 19 = − 4 + 19 − 7 x + 7 x 15 x = 15 15 15 x = 15 15 x = 1 To prove: 8 − 19 = − 4 − 7 − 11 = − 11 Therefore x≠5
Answer:
X=5
Step-by-step explanation:
No, x = 5 is not a solution to the equation 8 x − 19 = − 4 − 7 x . The correct solution is x = 1 . We confirmed this by substituting x = 1 back into the original equation.
