Evaluate 5x-7y when x 4 and y 2

WebThe answer above was not correct... you take -5x+2y=22 and multiply the whole equation by four to get: -20x+8y=88, and then you can subtract the other original equation: 9x+8y=30 from it... and you get -29x=58, so you divide -29 on both sides, which gives you x=-2... then to find y you simply plug this into the equation: 9 (-2)+8y=30 and you get … WebSolve for x: 3e^ {3x} \cdot e^ {-2x+5}=2 3e3x ⋅e−2x+5 = 2.
