Answer:
x=3
Step-by-step explanation:
3x=y y=9
fill y in with 9
3x=9
÷3 ÷3
x = 3
3x = y
y = 9
Put y as 9 into the first equation and solve for x.
3x = (9)
Divide both sides by 3.
x = 9/3
The correct answer to this question is Option (4).
X=-3/2
-2(x+2)=-1
Distribute
-2*x and -2*2
-2x-4=-1
Solve for x
+4 +4
-2x=3
/-2 /-2
x=-3/2
wrong the answer is 63.1
