Explanation

3x + 4y = 16

3x = 16 - 4y

3x = 4 ( 4 - y)

x = 4(4 - y)/3

X= 16 /3 - 4y/3

Answer:

3x + 4y = 16 The rule is you can do any valid operation on both sides of an equation and it will still be equal. Subtract 4y.

3x = -4y + 16 Divide by 3.

x = -4y/3 + 16/3 Answer B.

(5x – 3y + 8) + (-3x + 6y - 3)

Wewaii [24]

Answer:

2x+3y+5

Step-by-step explanation:

Firstly, we remove the parenthesis since there is nothing in front of it.

There is a “+” sign in front of the parenthesis, it stays the same.

Secondly, we combine like terms. We combine the x’s, the y’s, and the normal numbers without a variable.

Finally, after combining the like terms. You end up with “2x+3y+5”.
