Solve for each system of equations 2x + 3y = 10, 3x + 2y = 5
u know how to solve it?
No idea.
there are two way to do it, subtitution and elimination u know any of it?
nope, i never learned any of it. I was homeschooled from 5th-12th grade. and it was some stupid books that taught me nothing so i've been tying to teach myself everything on my own, and yeah.
okay, so substitution is just changing one of the variable value, like your previous question
and elimination is yeah it eliminate one of the variable
\[2x+3y=10\]\[2x=-3y+10\]\[x=-\frac{ 3 }{ 2 }y +\frac{ 10 }{ 2 }\]
that the substitute value of X, so just change X with that
@ArifL 2 other methods are using matrix and graphing
yeah, but it will be abit complex for matrix
(4x - 6)(6x - 4) A. 24x^2 + 24x + 24 B. 24x^2 - 52x + 24 C. 24x^2 + 52x -24 D. None of these so what would this be?
\[(ab) \times (cd) = ac+ad+bc+bd\]
and thanks for reminding me @triciaal
