Question

write equation in terms of Y. 2x - 4 is equal to 9​

Answer 1

Answer

1)2x+y=9⟹y=9−2x

x=1 then y=9−2(1)=7

x=0 then y=9−2(0)=9

x=2 then y=9−2(2)=5

x=3 then y=9−2(3)=3

(0,9),(1,7),(2,5),(3,3) are four solutions

Answer 2

Answer:

True

Step-by-step explanation:

2x-4=9

Let's find out the value of x and see whether it is true or false

2x means that 2 is multiplied by x

2x-4=9

By linear equation

2x=9+4

2x=13

x=13/2

x=6.5

So not we will put the value of x and see the answer

2×6.5-4=9

13-4=9

9=9

LHS=RHS

Hope it helps

This is true.
