What is the y-value of the solution to the system of equations? 3x+5y=1 7x+4y=-13 -3 -1 2 5
Question
Answer:
The y-value of the solution to the system of equations is 2.We have given a system of equation3x + 5y = 17x + 4y = −13What is the system of equation?A system of equations is a collection of two or more equations with the same set of unknowns.First we have to find the value of x.3x + 5y - 5y = 1 - 5ydivide both sides of the equation by 33x/3 = 1/3 - 5y/3x = 1/3 - 5/3yNow plug that into the other equation,7(1/3 - 5/3y) + 4y = -137/3 - 35/3y + 4y = -137/3 - 7 2/3y - 7/3 = -13 - 7/3- 7 2/3y (-3/23) = -15 1/3 (-3/23)y = 2The answer is 2.To learn more about the system of equations visit:
