a(0.3−y)+1.1+2.4x (y−1.2) =0 =−1.2(x−0.5) consider the system of equations above, where aaa is a constant. for which value of aaa is there exactly one (x, y)(x, y)left parenthesis, x, comma, y, right parenthesis solution where y = 1.3y=1.3y, equals, 1, point, 3? round your answer to the nearest tenth.

The idea here is to use both equations to solve for “a” using the provided “y” value. In this case we can use the y=1.3 to solve for “x” in the second equation (yâ’1.2) = -1.2(x-0.5). Then, we can plug-in the value for “x” from the second equation into the first equation a(0.3â’y) + 1.1 + 2.4x = 0. The answer for “a” is 21/10=2.1.

That’s what i got when i looked up what the solutions were
