Answer:
x≥3/2
Explanation:
since we know that there is an unknown number being multiply with four, we're going to represent it as x:
(x*4)
It then multiply it with one:
(x*4)+1
And we know that it has to be 7 or greater than that:
(x*4)+1≥7
Now, we're going to do the math:
4 multiply with x is 4x
(x*4)+1≥7= 4x+1≥7
then, we're going to toss one to another side and minus it with seven
4x+≥7-1 = 4x+≥6
afterward, we divide everything by four to find what x is:
(4x+≥6)/4 = x≥3/2
