Start with the equation ( Y = -3x + 5 ). Substitute ( Y ) in the second equation with ( -3x + 5 ): 5x - 4(-3x + 5) = -3 Expand and solve for ( x ): 5x + 12x - 20 = -3 17x - 20 = -3 17x = 17 x = 1 Substitute ( x = 1 ) into the first equation to find ( y ): y = -3(1) + 5 y = -3 + 5 y = 2 So, the solution is ( x = 1 ) and ( y = 2 ).
