5x + 2y = 8, x + y = 4 If you want to solve the system of equations by addition, Multiply the second equation by -2 and add.
(x + y = 4) x (-2) =
(-2x - 2y = -8) + (5x + 2y = 8) =
3x = 0; x = 0/3; x = 0;
Plug x = 0:
5(0) + 2y = 8;
2y = 8; y = 8/2; y = 4

Find two consecutive integers whose sum is 73. Which of the following equations could be used to solve the problem?
Weegy: x + (x + 1) = 73; 2x + 1 = 73; 2x = 73 - 1; 2x = 72; x = 72/2; x = 36, the next integer is 37. 36 + 37 = 73. The equation 2x + 1 = 73 could be used to solve the problem. (More)
