5(10)-y=54
50-y=54
-y=54-50
-y=4
y=4/-1
y=-4
hope its help you
Answer:
x > 10
Step-by-step explanation:
x-3 > 7
Add 3 to each side
x-3+3 > 7+3
x > 10
Your answer would be 9/27 but can be converted to 1/3. Hope this helps
Using substitution:
first you have to express one variable in terms of the other, in this we can express y in terms of x:
Since both expressions are equal to y, you have to equal both expressions like this:
Now you can solve the equation:
Knowing x=10, you can use any of the expressions we found before to find y. In this case I'm going to use y= -x+9 because it's simpler but boy should give you the same result
So, the answer is x=10 and y=-1
