A first number plus twice a second number is 55. Twice the first number plus the second totals 1313. Find the numbers.
Sphinxa [80]
The answer: x=857 and y=-401

Set up the two equations

X+2y=55
2x+y=1313

Solve the system of equations by elimination

2x+y=1313
-2x-4y=-110

Add each of the corresponding terms together

-3y=1203

Divide by -3

Y=-401

Plug y back into one of the original equations

X+2(-401)=55
X-802=55
X=857

Ok so you would take the bottom which is 15 and divide that by half of 15 which is 7.5. Then you would take the answer (2) and do an equation. You need to put BT at the end. In this case
it’s x = 2 + BT
