Solve the expression
$5(x-2)+3(x+1)=25$
Given : The expression is $5(x-2)+3(x+1)=25$
To do: Solve the expression
Solution:
$5(x-2)$
multiply 5 inside the brackets
$5 x - 10$
$3 (x + 1)$
multiply 3 inside the brackets
$3 x + 3$
Now, adding the terms
$5 x - 10 + 3 x + 3 = 25$
$5 x + 3 x - 10 + 3 = 25$ [add variables and numbers separately]
$8 x - 7 = 25$
$8 x = 25 + 7$ [- 7 becomes + 7 when it comes to other side]
$8 x = 32$
$ x = \frac{32}{ 8}$
$x = 4$
Therefore, the value of $x \ is \ 4$
