Select the correct statement about step 3
A When the equations -10x5y60 and 3x - 5y5 are added together, a third linear equation-13 -65, is formed, and it
has a different solution from the orignal equations
B. When the equations-10x + 5y-60 and 3x - 5y5 are added together, a third linear equation. -13x*-65. is formed and it
shares a common solution with the original equations
.
10x Sy=-60. a third linear equation-13x.65.is formed and it shares a
When the equation-3x - 5y-Sis subtracted from
Common solution with the original equations
D. When the equation-3x - Syss is subtracted from 10x+ 5y-60. a third linear equation 1365.s formed and it has a
different solution from the original equations
