Problem on Equation solving

Equation solving is the problem of finding what values (numbers, functions, sets, etc.) fulfill a condition stated as an equality (an equation). Usually, this condition involves expressions with variables (or unknowns), which are to be substituted by values in order for the equality to hold. More precisely, an equation involves some free variables.you will get this in 7th grade math equations

In one general case, we have a situation such as

f(x₁,...,x_n) = c,

where c is a constant, which has a set of solutions S of the form

{(a₁,...,a_n) ∈ Tⁿ|f(a₀,...,a_n) = c}

with Tⁿ the domain of the function which is in relations and functions . Note that the set of solutions can be empty (there are no solutions), singleton (there is exactly one solution), finite, or infinite (there are infinitely many solutions).

Let's see how to solve equations

Question:-

Solve for y

7x-(3/4)y = 5

Answer:-

7x-(3/4)y = 5

subtract 7x on both sides

-(3/4)y = -7x+5

then multiply both sides by -4/3
so as to get only y on the left hand side

y = -4/3(-7x+5)

y = (28/3)x - 20/3
