74 divided 1/2 =144 hope this helps!
I believe it is 52. All you do is take 156 and divide it by 3. You get 52. In order to check if this is true, you take 52 and add it 3 times.
Um.. Both of those equations are the exact same. Divide both sides of the first equation by 6. You get:
That is the exact same as the second equation. This system has an infinite number of solutions. 5x - 7y = -1 is a line, so basically every point on that line is a solution to the system.
For example,
and
would work, but so would
and
Answer:
(6,0)
Step-by-step explanation:
Answer:
8x-7y=-25
Step-by-step explanation:
It's a matter of substituting the x and y values into the equations
so basically trial and error
I used the set of points: (-4, -1)
(8 x -4)-)7 x -1) = -25
