Answer:

y = -3/4x-5/2 and y = 2/3x-1/3

Step-by-step explanation:

y+1 = -3/4(x+2)

y+1 = -3/4x-3/2

y = -3/4x-3/2-1

y = -3/4x-5/2

-----

y-3 = 2/3(x-4)

y-3 = 2/3x-8/3

y = 2/3x-8/3+3

y = 2/3x-1/3

Easy question i will mark braineliest

Yuki888 [10]

Answer:

Step-by-step explanation:

$5(y - 3.8) = 4.7(y - 4)$

Distribute 5 through the parentheses

$5y - 19 = 4.7(y - 4)$

Distribute 4.7 through the parentheses

$5y - 19 = 4.7y - 18.8$

Move ' 4.7 y ' to L.H.S and change it's sign

$5y - 4.7y - 19 = - 18.8$

Move constant to R.H.S and change it's sign

$5y - 4.7y = - 18.8 + 19$

Collect like terms

$0.3y = - 18.8 + 19$

Calculate

$0.3y = 0.2$

Divide both sides of the equation by 0.3

$\frac{0.3y}{0.3} = \frac{0.2}{0.3}$

Calculate

$y = 0.67$

Hope this helps...

Best regards!!
