Enter (without the quotation marks) "$==>$" if the left equation implies the right, "$<==$" if the right equation implies the left, "$<==>$" if either equation implies the other, and "$><$" if neither equation implies the other.

$5x+3 = 2x - 4$ $3x+3=-4$. (Subtract $2x$ on both sides.)

$3x+3=-4$ $3x=-7$. (Subtract 3 on both sides.)

$3x=-7$ $x=-\frac{7}{3}$. (Divide by 3 on both sides.)

Note: this problem illustrates the logic of solving a simple linear equation.
