Answer:
x = -2
Step-by-step explanation:
6 more then the product of 5 and a number x is -4
" the product " means multiply
5x + 6 = -4
5x = -4 - 6
5x = -10
x = -10/5
x = -2 <===
If x = 7 we just substitute all the x's by seven, so our equation stays like this:
5 - 3(7 - 1)
Now we solve it:
5 - 3(7 - 1) =
5 - 3(6) =
5 - 18 =
-13
