Solve the system of equations by the substitution method x + 3y = 32-3x + 2y = 3 x = 32 3y-3(32-3y)+2y=3-96+11y=3 11y = 3 + 96 11y = 99 y = 99/11 y = 9 x + 3(9) = 32 x+27=32 x=32-27 x=5 4. Solve the system of equations x + y = 5 Module 3 Case Assignment 5 x - y = -9 2x=-4 x=-4/2 x=-2 -2+y=5 y=5+2 y=7 5. Ricks Paint Store sells a special shade of pink paint (Ricky's Blush) which can be made from red paint and white paint. The amount of red paint should be three times the amount of white paint.
