You will have new classes to come at advanced stages of your studies that depend on these things. My advice to you is to love mathematics as much as possible .
Answer:
x=
−2
/7
y+
−17
/7
Step-by-step explanation:
well 3y and -y together make 2y. 2x and 5x make 7x. -5 and -12 make -17. then you get 7x+2y=-17. Let's solve for x.
7x+2y=−17
Step 1: Add -2y to both sides.
7x+2y+−2y=−17+−2y
7x=−2y−17
Step 2: Divide both sides by 7.
7x
7
=
