Answer:
y = 3/2( x-v)
Step-by-step explanation:
2/3y + v = x
Subtract v from each side
2/3y + v-v = x-v
2/3y = x-v
Multiply each side by 3/2
3/2 *2/3y =3/2( x-v)
y = 3/2( x-v)
Answer:
104
Step-by-step explanation:
232-128=104
3x + 2y = 10 ....multiply by -4
12x + 5y = 25
-------------------
-12x - 8y = -40 (result of multiplying by -4)
12x + 5y = 25
------------------add
-3y = - 15
y = -15/-3
y = 5
3x + 2y = 10
3x + 2(5) = 10
3x + 10 = 10
3x = 10 - 10
3x = 0
x = 0
solution is (0,5)
