elimination method 4p+3q=6 and 3p-5q=-10

Answer 1

multiply the equations by factors to equalize the p or q coefficients between the equations

then add or subtract the resulting equations to eliminate p or q

solve for the variable , then substitute back to find the other variable

Answer 2

like:
3(4p+3q=6) and 4(3p-5q=-10 )
is
12 p + 9 q = +18
12 p - 29 q = -40
