Evaluate 4(2a – b) when a = –1 and b = 5. –48

–28

–12

32

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

4+(2+x) can you me solve this problem

Y=21.95x+10 y=22.45x solve by substitution
