Answer:
-3
Step-by-step explanation:
The product (the result of a multiplication) of 4 and a number. Let x be the unknown number:
4 · x = 4x
Plus 17:
4x + 17
Is 5:
4x + 17 = 5
Solve:
4x = 5 - 17
4x = -12
x = -12 ÷ 4
x = -3
Step-by-step explanation:
5x - 4 = 2x + 6 × x
-----> 5x-3x = 6 + 4
-----> 2x = 10
----> x = 5
