The solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.
What is an arithmetic operation?
It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
We have a mathematical equation:
6(2x - 11) + 15 = 21
DIstributive property:
12x - 66 + 15 = 21
Subtraction property:
12x -51 = 21
Add 51 on both side:
12x -51 + 51 = 21 + 51
12x = 72 (adding like terms)
x = 6 (divide by 12 on both side)
Thus, the solution to the equation is 6 if equation is 6(2x - 11) + 15 = 21 the answer is 6.
