Answer:
4.87 to the fourth power
Step-by-step explanation:
Let's multiply the first equation by 3. (As you can see y's coefficient in the first one is 1 and in the second one is -3 , we will multiply the first equation by 3 so when we add the equations their sum will be 0)
Now let's add this new equation and our second equation.
We found x=-3
Now let's plug x's value in one of the equations to find y's value.
So we found y=5
Solution ;
(-3, 5)
Answer:
36+30 = 6(6+5)
Step-by-step explanation:
We just simply expand the brackets:
6×6=36
6×5=30
30+36=76
so 76-36=30
So the missing number was 30
Answer:
if you solve the equation it is 8 but the equation is 5-(-3) or 5+3 because two negatives equal a plus
