Answer: 
Step-by-step explanation:
This is a multiplication problem. You are multiplying 
by 4. This also means 4 divided by 3. They are both the same.
You just have to find what x is. Pretend there isn't the signs and think of it as = signs. Then whatever u do on one side do it to all of them
Answer:
d) x+y = 4
Step-by-step explanation:
(−1, 5) and (1, 3)
y = mx + b
m = (3 - 5) / (1 - (-1)) = -2 / 2 = -1
b = y - mx = 3 - ((-1) x 1) = 4
equation: y = -x + 4
Answer:
x = -4
Step-by-step explanation:
2 - (7x + 5) = 13 - 3x
add the binomial (7x +5) to both sides
2 = (7x + 5) + 13 - 3x
combine like terms
2 = 4x + 18
subtract 18 from both sides
-16 = 4x
divide by 4
x = -4
