Question

Is (2,-2) a solution to the system of equations.9x = 10 - 4yу = 3х - 8-

Answer 1

Solution;

Given the system of equations below

`\begin{gathered} 9x=10-4y...(1) \\ y=3x-8...(2) \end{gathered}`

To find out if (2, -2) is the solution to the given system of equations, we solve for x and y

Applying the substitution method to solve the system of equations

Substitute for y in equation (1)
