Question

x + y = 3500, x - 10x/100 + y - 8y/100 = 3170, solve using elimination method​

Answer 1

Answer:

y=-60/-20 y=3 2x+4(3)=16 2x=16 - 12 x=2. R= x=2 y=3 3x+2y= 7 4x-3y= -2 ... x=66/7. R=x=66/7 y= -15/7 x+y=3500 x-10x/100 + y-8y/100=3170

Explanation:

Solving Systems Of Equations By Elimination Method ... 4x + 8y = 6 ….(4) ... Verification: Both the equations are satisfied by x = 3 and y = 4, which shows that the solution is correct. Example ... 3x + √10x = 5 ⇒ (3 + √10) x = 5.
