Describe equation.

In an equation, it is said that the values of two mathematical expressions are equal. The equality of two variables is established via a mathematical formula. It is denoted by the equal ('=') sign. For example, the formula is 8+2=12-2. The aforementioned equation indicates that the left and right sides of the equation are equal. In light of this, an equation is a claim that "this equals that."

Here,

S is the total families

thus,

S = 60 + 85 + 70 + 95 = 310.

I + II + III + IV = X

S = I + 2 II + 3 III + 4 IV

S - I = 2 II + 3 III + 4 IV

310 - 130 = 180 = 2 II + 3 III + 4 IV

Make III & IV = 0 to increase X.

2 II therefore equals 1800. II = 90

X max = 130+90 = 220

Therefore ,the solution to this equation question is option C) 220 .
