3(x+a) = b
To solve this equation, we need to isolate the variable.
Starting with 3(x + a) = b, we can begin by distributing the 3 to both terms inside the parentheses:
3x + 3a = b
Next, we can subtract 3a from both sides to get the x term by itself:
3x + 3a - 3a = b - 3a
Simplifying the left side:
3x = b - 3a
And finally, dividing both sides by 3:
3x/3 = (b - 3a)/3
Simplifying further:
x = (b - 3a)/3
So, the solution to the equation is x = (b - 3a)/3.
