Step-by-step explanation:
RS=S-R
=(-1,-1)-(4,4)
=(-1-4,-1-4)
=(-5,-5)
Ax +c/3 =d now we can make crisscross
ax+c =3d now find value of x
ax=3d-c positive c become negative when I turn to other equal side
so
ax=3d-c
x=3d_c/a
I think 6 but I’m not sure also how I got this answer is by simplifying 3/2 to 1 and a half so than I did 7 and a half - 1 and a half
