Solve the equation: -8(2a-1)=36
SashulF [63]

The solution to the given equation is \frac{-7}{4}.

<h3>What is an expression?</h3>

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context. An expression is a combination of numbers, variables, or a combination of numbers and variables, and symbols and it is connected by the sign of equal.

We have,

Expression -8(2a - 1) = 36

So,

Now,

To get the solution to this expression,

i.e.

-8(2a - 1) = 36

Rewrite it as,

i.e.

Opening Brackets,

We get,

-16a + 8 = 36

Now,

Taking variable terms on one side and other terms on another side,

We get,

-16a = 36 - 8

On solving we get,

-16a = 28

i.e.

a = \frac{-28}{16} = \frac{-7}{4}

So,

The solution to the given equation is \frac{-7}{4}.

Hence, we can say that the solution to the given equation is \frac{-7}{4}.
