    The first expression on the left just requires you to combine the like terms on the inside of the parentheses.

    That would be\[4x + 2y +x - y = (4+1)x + (2-1)y = 5x + y\]

    Well, you just need to plug in those values of x and y.

    That's the first term. Then you need to compute\[5.2 y = 5.2 \times 2 = 10.4\]
