Find the volume of the solid formed by rotating the region enclosed by y=e^4x+3 y=0 x=0 x=0.7 this is my work V = ∫ e^4x dx {between x=0 and x=0.7} = 1/4 e^4x {between x=0 and x=0.7} = 1/4 (e^2.8 - e^0) = 1/4 (e^2.8 - 1) however i am etting the wrong answer pls help!!!

solve by sustution 9x+2y=-64 -6x+y=52 what is the solution set I came up with (-6,2) am I right

algebra
solve by substitution, 9x+2y=-64
