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.
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.

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

since BC=1/2 AC you take half of 54 then solve the equation. 3x^2=54/2 3x^2=27 x^2=9 x=3
