SOLUTION: Evaluate the expression for x=3 and z=4 4xz-3x= I got 127 I did 4(34)=136 minus 3(3)=9 so I did 136-9 =127 and I got it wrong ...where did I go wrong and what's the correct awns

Evaluate the expression for x=3 and z=4 4xz-3x= I got 127 I did 4(34)=136 minus 3(3)=9 so I did 136-9 =127
-----------
4xz-3x
= 4*3*4 - 3*3
= 48 - 9
= 39
==================
4(34)=136
4xz mean 4 times x times z --> 4*3*4, not 4 times 34
