x =
Step-by-step explanation:
8x−5y=11 = Let's solve for x.
8x−5y=11
Step 1: Add 5y to both sides.
8x−5y+5y=11+5y
8x=5y+11
Step 2: Divide both sides by 8.
8x

=
5y+11

4x−3y=5= Let's solve for x.
4x−3y=5
Step 1: Add 3y to both sides.
4x−3y+3y=5+3y
4x=3y+5
Step 2: Divide both sides by 4.
4x

=
3y+5

- 52 x 1/5 + 4 = - 6.4
-12 x 1/5 - 4 = -6.4
The answer is 1/5
