Can someone please explain how to do this!! I’ve been stuck for awhile A system of equation is shown below equation A: 5x+9y=12 Equation B: 4x-3y=8 Which method eliminates one of the variables A. Multiply equation b by 3 and add to equation a B. Multiply equation b by 5/4 and add the results by equation a C. Multiply equation a by -1/3 and add the results to equation b D. Multiply equation a by 4/5 and add the results to equation b

(05.02)a farmer has decided to divide his land area in half in order to plant soy and corn. calculate the area of the entire area so he knows how much soil is needed. a parallelogram with a height of 6 yards and side length 9 yards. the height forms a triangle with the slanted side of the rhombus with a base of 2.5 yards. rhombus is split into a soy half and a corn half. each bag of soil covers 40 square yards. how many bags should the farmer purchase?
