It is simple -8xy - 10 + x. That cannot be simplified further.
2x + 4y = 72x - 2x + 4y = 7 - 2x4y = -2x + 74y/4 = -2x/4 + 7/4y = -(1/2)x + 7/4Now that y is a function of x, you can give some values for x and find the corresponding values for y. (There are infinitely values for x an y)
76 plus 54 plus 92 plus 88 plus 76 plus 88 plus 75 plus 93 plus 92 plus 68 plus 88 plus 76 plus 76 plus 88 plus 80 plus 70 plus 88plus 72 equal 1,440
It is 77

The answer is 672.
27x3+6=87.
