Answer:
x=−1.481481
Step-by-step explanation:
Let's solve your equation step-by-step.
19.2x+3=(4.6)(3)x−5
Step 1: Simplify both sides of the equation.
19.2x+3=(4.6)(3)x−5
19.2x+3=13.8x+−5
19.2x+3=13.8x−5
Step 2: Subtract 13.8x from both sides.
19.2x+3−13.8x=13.8x−5−13.8x
5.4x+3=−5
Step 3: Subtract 3 from both sides.
5.4x+3−3=−5−3
5.4x=−8
Step 4: Divide both sides by 5.4.
5.4x
5.4
=
−8

x=−1.481481
Answer:
x=−1.481481
Answer:
see explanation
Step-by-step explanation:
(1)
x² - 6 = 2 - 18x ( add 18x to both sides )
x² + 18x - 6 = 2 ( add 6 to both sides )
x² + 18x = 8
to complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(9)x + 81 = 8 + 81
(x + 9)² = 89
(2)
(x + 9)² = 89 ( take square root of both sides )
x + 9 = ±
( subtract 9 from both sides )
x = - 9 ±
