Solve for:
x
Let's solve for x.
−2x+2y=−2
Step 1: Add -2y to both sides.
−2x+2y+−2y=−2+−2y
−2x=−2y−2
Step 2: Divide both sides by -2.
−2x
−2
=
−2y−2
−2
x=y+1
Answer:
x=y+1
2. Let's solve for x.
3x+2y=8
Step 1: Add -2y to both sides.
3x+2y+−2y=8+−2y
3x=−2y+8
Step 2: Divide both sides by 3.
3x/3=-2y+8/3
x=-2/3 y+8/3
Answer:
x= -2/3 y+8/3

↪ By Substitution method
⇒Eq.1
Soo value of y => y = 2x-2
↪ Substituting y= 2x-2 in ( 3x+2y = 8)
- 3x+2(2x-2)=8
- 3x+4x-4=8 (solving like terms)
- 6x=12

- x = 2
↪ Substituting x = 2 in eq 1 to get y
- -2x+2y=-2
- -2(2)+2y=-2
- -4+2y=-2(solving like terms)
- 2y= -2+4
- 2y= 2

- y=1
↪ hence, (2,1) is the solution ~

Step-by-step explanation:
Well you don’t need to count in mr smiths math class because all the classes has 54 so um I did 4x54 hoped this helped :)
<span>If y = x^3 - 3 if x = 3
y = 3^3 - 3
y = 27 - 3
y = 24</span>
