Answer:
Given the equation:
[tex]7(x-4) = 84[/tex]
Using the distributive property, i.e, [tex]a \cdot (b+c) = a\cdot b+ a\cdot c[/tex] we have;
[tex]7x -28 = 84[/tex]
Add 28 to both sides we have;
[tex]7x = 112[/tex]
Divide both sides by 7 we have;
[tex]x = 16[/tex]
⇒value of x is, 16
Following Steps are as follow:
[tex]7(x-4) = 84[/tex]
[tex]7x -28 = 84[/tex]
[tex]7x = 112[/tex]
[tex]x = 16[/tex]
