Simplifying 4y + -70 = 12y + 2

Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y

Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.

So y = -9 is your answer.

Can you help me to solve this

Ber [7]

Answer:

$\frac{4a-2}{2a+1}$

Step-by-step explanation:

Factorise the numerator and denominator

8a² - 2 ← factor out 2 from each term

= 2(4a² - 1) ← 4a² - 1 is a difference of squares

= 2(2a - 1)(2a + 1)

4a² + 4a + 1 ← is a perfect square

= (2a + 1)²

Thus

$\frac{8a^2-2}{4a^2+4a+1}$

= $\frac{2(2a-1)(2a+1)}{(2a+1)(2a+1)}$ ← cancel (2a + 1) on numerator/ denominator

= $\frac{2(2a-1)}{2a+1}$

= $\frac{4a-2}{2a+1}$
