Would you help me solving these from Algebra. Thank you very much.

Find the complete solution of the linear system, or show that it is inconsistent. (If the system has innitely many solutions, express your answer in terms of t, where x = x(t), y = y(t), and z = t. If there is no solution, enter NO SOLUTION.) X2y32=7 2x+ y z 7 4X3y7z=7 (x, y. z) =( ) A farmer has 1,150 acres of land on which he grows corn, wheat, and soybeans. It costs $45 per acre to grow corn, $60 to grow wheat, and $50 to grow soybeans. Because of market demand the farmer will grow twice as many acres of wheat as of corn. He has allocated $61,250 for the cost of growing his crops. How many acres of each crop should he plant? corn l acres wheat l acres soybeans l acres Use the substitution method to nd all solutions of the system of equations. {y = *2 y = x + 30 (x, y) = ( ) (smaller x-value) (x, y) = ( ) (larger xvalue) Use the substitution method to nd all solutions of the system of equations. x2+y=4 X y+2=0 (x, y) = ( ) (smaller X-value) (x, y) = ( ) (larger xvalue) Two equations and their graphs are given.
