Question

find the following system of equations by the elimination method and the substitution method
y-2x=3
x-4x=2

Answer 1

$y - 2x = 3 - - - - eq1 \\ y - 4x = 2 - - - - eq2 \\ \\ subtracting \: 1\: by \: 2 \\ \\ 2x = 1 \\ x = 1 \div 2 \\ soy = 3 +2 \times 1 \div 2 \\ y = 3 + 1 \\ y = 4$
So solution is (1/2,4)
