Question

8x-5=2x+19
pls solve this and tell ​

Answer 1

Step-by-step explanation:

8x+5=2x+19

8x-2x=19+5

6x=24

x=24/6

x=4

Answer 2

when the -5 comes after the =symbol it becomes+5

8x=2x+19+5

=8x=2x+24

when the +24 comes after the before the = symbol it becomes -24

=8x-24=2x

That means 8x will be greater than 24

So let's take a multiple of 8 that is greater than 24

=32(8×4)

Now 8x = 8×4

x=4

8x-24=32-24

=8

that means 2x must be equal to 8

here we know x=4

therefore 2x=2×4=8

Now we proved that 8x-5=2x+19
