Question
Verify that the values of the variables listed are solutions of the system of equations.$$\begin{array}{l}\left\{\begin{array}{l}3 x+2 y &=2 \\x-7 y &=-30 \\ \end{array}\right. \\x=-2, y =4 ;(-2,4)\end{array}$$
Step 1
3(-2) + 2(4) = -6 + 8 = 2 The first equation is true with the given values of x and y. Show more…
