Question

8y - 4y = 20
solve as linear equation​

Answer 1

Answer:

y= 5 ( hope it is correct if yes mark as brainliest)

Step-by-step explanation:

8y – 4y = 20

⇒ 4y = 20

⇒ y = 20/4 = 5

∴ y = 5

Answer 2

Answer:

Your answer

$8y - 4y = 20 \\ = > 4y = 20 \\ = > y = \frac{20}{4} \\ after \: cancellation \\ y = 5$

Verification

$8y - 4y = 20 \\ substitute \: 5 \: in \: y \: \\ 8(5) - 4(5) = 20 \\ = > 40 - 20 = 20 \\ 20 = 20 \\ hence \: verified$
