The value of x when y = 2 is x = 36
Step-by-step explanation:
The equation that we have in this problem is:
[tex]y=\frac{x}{4}-7[/tex]
In order to find the value of x when y is equal to
y = 2
We need to re-arrange the equation making x the subject.
We proceed as follows:
1) We add +7 on both sides:
[tex]y+7=\frac{x}{4}-7+7\\y+7=\frac{x}{4}[/tex]
2) Now we multiply both sides by 4:
[tex]4(y+7)=\frac{x}{4}\cdot 4\\x=4(y+7)[/tex]
3) Now we can substitute y = 2 and find the value of x:
[tex]x=4(2+7)=4(9)=36[/tex]
