Write the problem as a mathematical expression.

$4a+6b=-2$

$2a+4b=-1$

Solve for $a$ in $4a+6b=-2$.

$a=-\frac{1}{2}-\frac{3b}{2}$

$2a+4b=-1$

Replace all occurrences of $a$ with $-\frac{1}{2}-\frac{3b}{2}$ in each equation.

$-1+b=-1$

$a=-\frac{1}{2}-\frac{3b}{2}$

Move all terms not containing $b$ to the right side of the equation.

$b=0$

$a=-\frac{1}{2}-\frac{3b}{2}$

Replace all occurrences of $b$ with $0$ in each equation.

$a=-\frac{1}{2}$

$b=0$

List all of the solutions.

$a=-\frac{1}{2},b=0$
