Answer:

5 1/12

Step-by-step explanation:

What you should do is find the common denominator for all of these numbers, which is 12.

Now you have to multiply the fraction part so the denominator equals 12.

1*6/2*6= 6/12

3*3/4*3= 9/12

5*2/6*2= 10/12

Now you have to add up all of these numbers

2+6/12+1+9/12+10/12= 3 25/12, which simplified would equal 5 1/12.

Switch the second equation to equal y so...
y=-2x-3
then plug in for y in the first equation
2x+4(-2x-3)=6
2x-8x-12=6
-6x=18
x=-3
now plug in for y
2(-3)+y=-3
-6+y=-3
y=3

KATRIN_1 [288]

Answer:

(11+x)-3

Step-by-step explanation:

11 more than x is another way of saying 11+x

And "less than 3" means subtracting 3 from the terms

So if you put that together it would be

(11+x) -3
