Question

for what value of x , y=z where y=2x+3 and z= 9-5x.

Answer 1

Answer:

7/6

Step-by-step explanation:

Given that ,   y = 2x +3     and     z = 9 - 5x

And also , y = z

           => 2x +3 = 9 - 5x

           => 7x = 6

           => x = 7/6.

Answer 2

Answer:

∴ x = 6/7

Step-by-step explanation:

given,

 y = 2x + 3

z = 9 - 5x

y=z

2x+3 = 9 - 5x

or, 2x + 5x = 9 -3

or, 7x = 6

∴ x = 6/7
