3(x+2) = x -18
3x+6 = x -18
3x -x = -18 -6
2x = -24
x = -12
Add 5 to both sides of the equation to get rid of the - 5. -3x - 5 + 5 = -20 + 5 Solve and simplify. -3x = -15 Divide both sides of the equation by -3. x = 5
54 / 9 = n n = 6
Divide both sides of the equation by 12: x = 2
You cannot solve this equation without knowing the shape.
6 - 9w = 24 -9w = 18w = -2
18=3(3x-6)
By including its plus or minus signs
15x minus 8=minus 180 3x+8=24
60(x - 15) = 2500 (then simplify the left side of the equation) 60x - 900 = 2500 (then add 900 from both sides of the equation) 60x = 3400 (thn divide both sides by 60 to solve for x) x = 56.66666 (56-2/3)
It is an equation with the plus or minus signs missing which makes it impossible to solve.
Without an "equals" word or sign somewhere, there is nothing to solve.You only have an expression, not an equation.
x=2 because 9-(14)=-5

Parentheses is when you are doing an equation, and you solve the problem.

It can be solved by using the quadratic equation formula.
