Question

Please tell me the answer to 3c-9d+7c+5d

Answer 1

The answer to

3c-9d+7c+5d is 10c - 4d

Further Explanation

One variable linear equation is an equation that has a variable and the exponent number is one.

Can be stated in the form:

$\large {\boxed {\bold {ax = b}}$

or

ax + b = c,

where a, b, and c are constants, x is a variable

Whereas the two-variable linear equation is a linear equation that has 2 variables and the exponent is one

Can be stated in the form:

$\large {\boxed {\bold {ax + bx = c}}}$

x, y = variable

There are several ways to solve an equation

• Add / Subtract / divide / multiply the same value on both sides

• Combine like terms
• Factoring
• Expanding

Like terms are terms whose variables and their exponents are the same.

You can combine and add terms

The algebraic form of 3c-9d + 7c + 5d can be simplified:

• 1. Combine like terms

(3c + 7c) + (-9d + 5d)

• 2. Add like terms:

Answer 2

The simplest form of the expression $3c - 9d + 7c + 5d$ is $\boxed{10c - 4d}.$

Further explanation:

Always use the PEDMAS rule to solve the grouping of multiplication, addition, subtraction and division.

Here, P is parenthesis, E is exponents, M is multiplication, D is division, A is addition and S is subtraction.

Given:

The expression is $3c - 9d + 7c + 5d.$

Explanation:

The given expression is $3c - 9d + 7c + 5d.$

Consider the expression $3c - 9d + 7c + 5d$ as $A$.

$A = 3c - 9d + 7c + 5d$

Solve the above expression to obtain the simplest form.

$\begin{aligned}A&= 3c - 9d + 7c + 5d\\&= \left( {3c + 7c} \right) + \left( { - 9d + 5d} \right)\\&= 10c - 4d\\\end{aligned}$

The simplest form of the expression $3c - 9d + 7c + 5d$ is $\boxed{10c - 4d}.$
