could you walkthrough the steps to solving this problem because I am stuck;
3x5(3x7)=2(x+9)+45
Let me know if you have a question in any step.
3x5(3x7)=2(x+9)+45
3x15x+35= 2x+18+45
12x+35 = 2x+63
35 35
12x= 2x +6335
12x= 2x +28
2x 2x
12x2x = 28
14x= 28
14x/14= 28/14
x = 2
to check just substitute the answer for x to ever x in the original problem.
3x5(3x7)=2(x+9)+45
3(2)5(3(2)7)=2(2+9)+45
6 5 (67)= 2(7)+45
65(13)=14+45
6+65=59
59=59 it checks.
You really helped me out. I know see how to work out other problems like this one. Thank you very much!!!

you know that 8x = 5y you know that 3y=14z since 5 = (5/3)*3, 5y = (5/3)*(3y) so, 5y = (5/3)(3y) = (5/3)(14z) = (70/3)z now you have 5y, which is the same as 8x. You want 12x. since 12 = (3/2)*8, 12x = (3/2)*8x. 12x = (3/2)(8x) = (3/2)(5y) …
