Nataly Olson · 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.
