Answer:

Infinitely many solutions.

Explanation:

In this case we gonna use ELIMINATION BY ADDITION method.For that first we are gonna eliminate the terms containing ( X ).

Equation no 1:

3x + 3y = 10

Equation no 2:

-9x - 9y = -30

Now multiply equation no 1 with (3 )

3(3x + 3y) = 3(10)

9x + 9y = 30 ( equation no 1 )

Now ADD both the equations

9x + 9y = 30

<u> -9x - 9y =-30</u>

0 = 0

$\sf{\pmb{ANSWER : }}$

let the equation be

$\sf \: 3(y + 3) - 10 = 2y + 1$

$\sf \: 3y + 9 - 10 = 2y + 1$

$\sf \: 3y - 1 = 2y + 1$

$\sf \: 3y -2y = 1 + 1$

$\purple {{{\sf y = 2 }}}$
