Combine each pair of equations solve the combined equation 3j +14=-5z-10j=5z

ArbitrLikvidat [17]

Given data:

The first equation is 3j +14=-5z.

The second equation is -10j=5z .

Add both the equations.

$\begin{gathered} (3j+14)+(-10j)=-5z+5z \\ -7j+14=0 \\ 7j=14 \\ j=2 \end{gathered}$

Substitute 2 for j in the first equation.

$\begin{gathered} 3(2)+14=-5z \\ 20=-5z \\ z=-4 \end{gathered}$

Thus, the value of j is 2 and z is -4.

Answer:

1) 8 2) -33/9

Step-by-step explanation:

1) (1/2)x = -1/2 + 9/2

(1/2)x = 4 x = 8

2) distributing 3/2, 9x/2 - 15/2 = -24

9x/2 = -24 + 15/2

9x/2 = -33/2

9x = -66/2

9x = -33

x = -33/9
