The equations were multiplied by constants and added together to determine that the value of x in the system of equations is –4. Negative three-fourths x minus two-thirds y = negative 1 One-half x minus five-sixths y = negative 7 What is the value of y? a. –6 b. –3 c. 3 d. 6

Option d. 6

Step-by-step explanation:

we have

----> equation A

-----> equation B

Multiply the equation A by -5/4 both sides

-----> equation C

Adds equation B and equation C

Find the value of y

substitute the value of x in equation A

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.
