By following BODMAS, evaluate the inner brackets first, collecting terms together as you go:
B - 3(B - 4(1 - B)) = 54
→ B - 3(B - 4 + 4B) = 54
→ B -3(5B - 4) = 54
→ B - 15B + 12 = 54
→ -14B = 42
→ 14B = -42
→ B = -3
Check by substituting back into the original equation:
B - 3(B - 4(1 - B))
→ -3 - 3(-3 - 4(1 - -3))
→ -3 - 3(-3 - 4(4))
→ -3 - 3(-3 - 16)
→ -3 - 3(-19)
→ -3 + 57
→ 54 as required.

54A-524=340. Add 524 to both sides. 54A=824. Divide by 54. There's the answer.
You cannot. x - 54 is an expression not an equation. An expression has no solution set since there is nothing to solve.
54 / 9 = n n = 6
Assuming this is all he does to solve the equation, it would look like this: 9y = 54 He solves this by dividing 54 by 9: y = 54/9 y = 6
54x1 and 6x9 = 54

2x + 33x - 54 35x - 54 We can not find x with the information given. You need to equate somethingto your equation. If your equation equals 0 then... 0=35x-54 35x=54 x=1.543 IF your equation equals x then... x=35x-54 -34x=-54 x=1.588
i think you should add them
54A-524=340. Add 524 to both sides. 54A=824. Divide by 54. There's the answer.
You cannot. x - 54 is an expression not an equation. An expression has no solution set since there is nothing to solve.
To find out what number multiplied by 18 equals 54, you can set up an equation: 18x = 54. To solve for x, divide both sides by 18: x = 54 / 18. Simplifying the division gives x = 3. Therefore, 18 times 3 equals 54.
