(6.03) what is the constant term in the expression 6x3y + 7x2 + 5x + 4? (input a numeric value only.) numerical answers expected! me pls! fast pls

3x + 4y = 5 x- 3y = -7 solve by substitution

Suppose y varies directly with x. write a direct variation equation that relates x and y. then find the value of y when x=12 y=7 when x=3
