Question

2z+7/3z+8=1/4 solve​

Answer 1

Answer:

Step-by-step explanation:

(cross multiplication)

4(2z+7) = 1(3z+8)

8z+28 = 3z+8

8z-3z = 8-28

5z = -20

z = -20/5

z = -4

Answer 2

Given:

2z+7/3z+8=1/4

To find:

The value of z

Solution:

The value of z is -4.

We can find the value of z by following the given steps-

We know that the given equation can be solved by using cross multiplication.

We are given that 2z+7/3z+8=1/4.

We will multiply the numerator with 4 and multiply the denominator with 1.

4(2z+7)=1(3z+8)

8z+28=3z+8

8z-3z=8-28

5z= -20

z= -20/5

z= -4

Therefore, the value of z is -4.
