3x+11 = 32
3x = 32-11
3x = 21
The solution is: x = 7
11 and 11. In general, you can write an equation (or two equations), and solve with the quadratic formula, to solve this type of questions.
(-11) + (-12) + -(13) = -36
Set up a system of equations. Let the numbers be x, y. X + Y = 153X = 5Y-11 Solve the first equation for Y.Y = 15-XPlug it into the second equation.3X = 5(15-X) - 11And solve for X.3X = 75 - 5X - 113X = 64 - 5X8X = 64X = 8 Plug X back into the original first equation.8 + Y = 15Y = 7 X = 8, Y = 7
3 (11+6) It means eleven plus six which is seventeen and then times by three. Or if that isn't what you wanted maybe get rid of the three and add a cubed sign behind the bracket.
The integers are 11, 13 and 15.
It is an equation: 3x+11=32 and the value of x is 7
The algebraic expression for the sum of 11 times 5 and three is 11s+3

Maria is 11 years old.
To solve the equation, we first express it mathematically: (3(x - 7) = 12). Dividing both sides by 3 gives us (x - 7 = 4). Adding 7 to both sides results in (x = 11). Therefore, the number is 11.
