Respuesta :
x=15a/2. the way you get this is by simpifying both sides of the equation then isolate the variable. hoped this helped :)
5x-8a=3x+7a first solve for x by isolating x on one side of the equation
5x-3x-8a=7a subtract 3x from each side leaving 7a alone combine like terms
2x-8a=7a isolate x by adding 8a to both sides of the equation
2x=15a x=15a/2
