Answer:
y = 2
Step-by-step explanation:
3y - 4 = 6 - 2y
5y = 10
y = 2
Answer:
see explanation
Step-by-step explanation:
given
y = 3x² + 4 ( isolate the term in x by subtracting 4 from both sides )
y - 4 = 3x² ( divide both sides by 3 )
= x² ( take the square root of both sides )
= x, or
x = 
Answer:
x= 5 , y = 34
Step-by-step explanation:
8x-6=5x+9
3x-6=9
3x=15
x=5
-
8(x5) - 6 =
34
25(x5) +9 =
34
