Question

Solve for x. 3(-2x - 1) = 2(x + 5) A) - 13 8 B) - 3 4 Eliminate C) 13 8 D) 3 4

Answer 1

The answer is A) -13/8. Multiply first the constants outside the parenthesis with the terms inside. The equation will be -6x-3 = 2x+10. Then, combine like terms, terms with the variable X are grouped at one side while the constants are at the other. The equation is now -6x - 2x = 10+3. Shorten the equation by doing the operations. The equation is now -8x = 13. To get the value of x, divide the whole equation by -8 to eliminate the coefficient of x. Hence the answer is x = -13/8.
