Answer:
x = – ⅓
Step-by-step explanation:
The solution to the expression can be obtained as follow:
–3.1x + 7 – 7.4x = 1.5x – 6(x – 3/2)
Clear bracket
–3.1x + 7 – 7.4x = 1.5x – 6x + 9
–3.1x – 7.4x + 7 = –4.5x + 9
–10.5x + 7 = –4.5x + 9
Collect like terms
–10.5x + 4.5x = 9 – 7
–6x = 2
Divide both side by –6
x = 2 / –6
x = – ⅓
Thus, the solution to the equation is –⅓
It can be both because there are diffrent sizes
A multiplicative inverse is the same thing as a reciprocal, which is basically just flipping the fraction and changing the sign. Therefore the multiplicative inverse of -1/9 is 9

Answer:
The predicted value of x = 2
Step-by-step explanation:
y = 4.2x - 3 is the given equation.
Now, y = 5.4
Putting in the above equation, we get
5.4 = 4.2x - 3
or, 5.4 + 3 = 4.2x
or, 8.4 = 4.2 x
⇒ x = 8.4/4.2
⇒ x = 2
