You can say
x+y=5
x=5-y
You know the value of x, put it into the next equation.
3(5-y)-7y=19
15-3y-7y=19
15-19 = 10y
-4=10y
-4/10=y
-2/5=y
Put y value back into either equation to find value of x.
x+y=5
x-2/5=5
x=5+2/5
x=27/5
Therefore, x,y = (27/5, -2/5)
Hope I helped :)
Answer:
39/18 = 13/6 = 2 1/6

76% of students were not supportive.
you find the answer by gathering the total number of students not supportive over the total number of students. in this case it would be 
. then, you simplify it so that its a number over 100, so it would be 
. Then, you just convert that to a percentage, 76%
Answer=103 ounces
First we need a conversion equations to get from pounds to ounces
1pound=16ounce
2pounds=2*16=32 ounces of cucumber
3pounds=3*16=48 ounces of lettuce
Now that all of the vegetables are in ounces, we can solve for their total weight.
x=32+8+48+15=103 ounces
He bought 103 ounces of vegetables in total.
