Your method is right so u already know how to do it
The value of x is -8
Step-by-step explanation:
The steps of solving an equation of one variable
- Simplify the two sides of the equation
- Separate the variable in one side and the numerical term in the other side
- Divide the both sides by the coefficient of the variable
∵ 372 = -3x - 6(8x + 6)
- Simplify the R.H.S. of the equation by multiplying the bracket by 6
∵ 372 = -3x - [6(8x) + 6(6)]
- You must put the square bracket because the sign in-front of 6
is (-) and the (-) changes the signs after it
∴ 372 = -3x - [48x + 36]
- Remember (-)(+) = (-), multiply the square bracket by (-)
∴ 372 = -3x - 48x - 36
- Add the like terms in the R.H.S.
∴ 372 = -51x - 36
- Add 36 to both sides to separate x in the R.H.S.
∴ 408 = -51x
- Divide both sides by -51 (coefficient of x)
∴ -8 = x
I hope these steps help you

Answer:
X=SMALL BOX.
Y=LARGE BOX
THEREFORE,X+Y=21
X=21-Y
THEREFORE,25(21-Y)+70Y=1110 POUNDS
525-25Y+70Y=1110
525+45Y=1110
45Y=1110-525
45Y=585
Y=585/45
Y=13 .
Therefore,13 large box and8 small box..
