Varvara68 [4.7K]

To get the answer do this:

2.5% of what is 2.21

2.5%x = 2.21

divide both sides by 0.025

0.025x/0.025 = 2.21/0.025

Please help work this equation

Flauer [41]

Hi!

<u>Given these two equations:</u>

$x = y + 8$

$x + 4 = 2(y + 4)$

We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

$(y+8)+4=2(y+4)$
