Use a graphing calculator to solve the system of linear equations. 2.1x+4.2y=14.7 - 5.7x-1.9y=-11.4

I used my calculator and got x=1 y=3

solve for y to put them in your calculator

2.1x+4.2y=14.7

y = (14.7 - 2.1x) / 4.2

-5.7x-1.9y=-11.4

y = (-11.4 + 5.7x) / (-1.9)

then using the ploting tool I plotted them and found where they intersected
