Final answer:

he solution to the system of equations is x = 2 and y = 1/3.

Step-by-step explanation:

To find the solution of the system of equations:

y = -7/2x + 11

7x + 2y = 20

Choose a method to solve the system of equations. One option is to use the substitution method.

Start by solving the first equation for x, which gives us x = (11 - y) * 2/(-7).

Substitute this value of x into the second equation and solve for y:

7((11 - y) * 2/(-7)) + 2y

= 20.

Simplify the equation to obtain -8y + 22 + 2y = 20.

Combine like terms: -6y + 22 = 20.

Subtract 22 from both sides: -6y = -2.

Divide by -6 to solve for y: y = 1/3.

Substitute the value of y back into the first equation to find x:

x = (11 - 1/3) * 2/(-7).

Simplify the equation to obtain x = 2.

Therefore, the solution to the system of equations is x = 2 and y = 1/3.
