Question

Choose the replacement for x and y that makes this equation a true statement: 2x + 55y = −214

Answer 1

2x + 55y = -214
2(-24.5) + 55(-3) = -214
-49 - 165 = -214

x = -24.5
y = -3

(I think so anyways.)

Answer 2

there is an infinite number of solutions to this equation. Choose any number for x (which we'll call t) and rearrange the equation to isolate y (y=(-214-2x)/55) then y will be given from inserting t into the equation.

Answer 3

plotting the graph will give you all the possible combinations of x and y.
