Do you know if not don't answer What is 3x+1/5y=7

Mrac [35]

You will have to use trial and error in order to find the values for x and y.
Just keep plugging values until you get 7.

I found x is equal to 2 and y is equal to 5.

3(2) + (1/5)5 = 7
6 + 5/5 = 7
6 + 1 = 7
7 = 7

Suppose a friend is having difficulty solving -2(q-5) > -3(q+1). Explain how to solve the inequality, showing all the necessa

IgorC [24]

Firstly, use the distributive property of multiplication (A(B + C) = A×B + A×C) on -2(q - 5) and -3(q + 1): $-2q+10>-3q-3$

Next, apply the addition property of equality (whatever you add to one side you have to add the same quantity to the other), and add 3q on both sides: $q+10>-3$

Lastly, apply the subtraction property of equality (whatever you subtract on one side you have to subtract the same amount on the other side), and subtract 10 on both sides. <u>Your final answer will be $q>-13$ </u>
