Solve the system of equations 2 - 3y = -24 and 2x + y = 22 by combining the equations.

How do I do this on delta math. I’ve been trying to do this for an hour and nothing has helped.

List x1, x2, x3, x4 where xi is the left endpoint of the four equal intervals used to estimate the area under the curve of f(x) between x = 4 and x = 6. a 4, 4.5, 5, 5.5 b 4.5, 5, 5.5, 6 c 4.25, 4.75, 5.25, 5.75 d 4, 4.2, 5.4, 6
