Attempt following question by selecting a choice to answer. B
Solve the linear system.  x + y =  12 10x  y = 30cccc BBBBA. B(2,  10) B. B(10, 2) C. B(2, 10) D. B(10,  10) BB
A
Step 1: [Equation 1.] x + y =  12
Step 2: [Equation 2.]10x  y = 30 ___________
Step 3: [Add the equations.]9x = 18
Step 4: [Solve for x.] x = 2
Step 5: [Substitute x = 2 in Equation 1.] 2 + y =  12
Step 6: [Solve for y.]y =  10
Step 7: So, the solution for the linear system is (2,  10).
