Answer:
18
Step-by-step explanation:
To find x in a two-variable equation, all we have to do is to substitute y and isolate x.
We have our initial equation: 3x - y = 5
We know that y is 49, so we substitute this.
3x - 49 = 5
We isolate the asked term which is x by transposing y to the other side.
3x = 49 + 5
3x = 54
Finally, we divide both sides by 3 to find x.
3x / 3 = 54 / 3
x = 18
Therefore, if y is 49, the value of x in the given equation is 18.
Hope this helps!
