3x+5y=-3 x-5y=-5 show your work
frez [133]
We are given the equations 3x+5y=-3 and x-5y=-5.

Both equations have a 5y  term which allows us to easily solve the system by elimination. To do so we will add the equations together like a simple addition problem by adding the x terms together, the y terms together, and the integer answers together.

3x + 5y = -3
+x - 5y = -5
---------------
4x + 0y = -8

The y terms cancel out since one is positive and one is negative. Now we can solve for x.

4x = -8

\frac{4x}{(4)} = \frac{-8}{(4)}

x = -2

Now plug -2 in for x in one of the original equations to find y.

(-2) - 5y = -5

-5y = -3

y = 3/5

Our answer as an ordered pair is (2, 3/5)

Solve 4(x + 2) = 20
KiRa [710]

Answer:

x = 3

Explanation:

\sf 4(x + 2) = 20

\sf 4x + 8 = 20

\sf 4x = 20 - 8

\sf 4x = 12

\sf x = \frac{12}{4}

\sf x = 3

check:

4(x + 2) = 20

4(3 + 2) = 20

4(5) = 20

20 = 20

Hence proved x = 3
