can someone please check my answer for me? thanks in advance
9(x+4)=3(3x+2)+30
I got x=8
is this correct if not could you please tell me where I missed the step at?
It's right.
I checked it by substituting 8 for x in your original problem.
thank you
To check if your answer is correct, we can substitute the value of x that you obtained (x = 8) back into the original equation and see if both sides are equal.
Original equation: 9(x + 4) = 3(3x + 2) + 30
Substituting x = 8:
9(8 + 4) = 3(3(8) + 2) + 30
Now, let's simplify both sides of the equation:
Left side:
9(8 + 4) = 9(12) = 108
Right side:
3(3(8) + 2) + 30 = 3(26) + 30 = 78 + 30 = 108
Both sides are equal to 108, so your answer of x = 8 is correct. Well done!
