Solve the equation 7/z-1 = 9/z+4

algol [13]

Answer:

z is equal to 18.5

Step-by-step explanation:

When an equation is in the format a/b = c/d, the quickest way to simplify it is to cross multiply. Each side is multiplied by the other sides denominator, eliminating the division:

$\frac{7}{z-1} = \frac{9}{z + 4}\\7(z + 4) = 9(z - 1)\\7z + 28 = 9z - 9\\7z - 9z = -9 - 28\\-2z = -37\\z = 37/2\\z = 18.5$

So z is equal to 18.5

The system of equations 2y = 14 - 2x and y=-x+ 7 is

elena-s [515]

Answer:

Infinitely many solutions

Step-by-step explanation:

<u>Given system:</u>

2y = 14 - 2x
y = -x + 7

<u>Divide the first equation by 2 and rearrange:</u>

2y/2 = 14/2 - 2x/2
y = 7 - x
y = -x + 7

We got the same equation with the second one. It means we have two of the same lines overlapping.

This gives us infinitely many solutions.
