All we want to do is get an equation with just x on one side and no x's on the other.
We can use inverse operations to accomplish this.
First, bring bx to the left side. Subtract the 3.
Factor ax+bx to x(a+b). (this is pretty much reversing the distributive property)
Divide by a+b and you are left with just x on the left side as 4/(a+b).
Answer:
Isolate the variable by dividing each side by factors that don't contain the variable.
x = 4
i, - 4
i
The answer is B, 3/4 is greater than 3/5
3/4=0.75
3/5=0.6
0.75 is greater than 0.6
First check if the first two digits are divisible by 3 (45 / 3 = 15 So yes it is) And then if the first two are divisible by 3, then check if the next two are divisible by three, (12 / 3 = 4 ) Yes, so if both are, then yes the answer is divisible by three.
I think A is. y=m (-1) +4.
