Proof:

Given 3(x+1)=7(x-2)-3

To prove that the solution of 3(x+1)=7(x-2)-3 is 5,

3(x+1)=7(x-2)-3

On taking off the brackets we get,

3x+3=7x-14-3

On grouping the x terms together,

7x-3x=14+3+3

On solving we get,

4x=20

$x=\frac{20}{4}$

On dividing 20 by 4,

x=5

$\Rightarrow$ Hence proved that the solution for $\bold3(x+1)=7(x-2)-3\bold$ is 5.

i think it's y=2

Step-by-step explanation:

because if u do 18x3=54, all gotta do is divide 6 by 3 and u get 2.
