You can solve this by equation the two equations, by substitution method or elimination. Let's choose the substitution since Equation 2 has already X isolated -take the X in equation 2 and substitute in the first equation So, You should have 5 (5-3/2 y) -4y =7 Get y ( I'll assume you know how to simplify and find y by yourself ) y=36/23 -Now take y and substitute it in the first equation or the second equation (it doesn't really matter) Substituting y in Equation 2: x=5- 3/2 (36/23) => x= 61/23
