7x the answer i think

Step-by-step explanation:

Answer 2

Answer:

$\boxed {\boxed {\sf -2 \ is \ not \ a \ solution}}$

Step-by-step explanation:

We are asked to check is -2 is the solution of the following equation.

$2-x= 4x+3$

We must substitute -2 in for x and solve both sides of the equation. If the two sides are equal, then -2 is the solution.

$2- (-2) = 4(-2)+3$

Solve both sides of the equation according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

Let's start with the left side.

$2+2= 4(-2)+3$

$4= 4(-2)+3$

Now solve the right side. Remember to multiply first.

$4= -8+3$

$4= -5$

$4\neq -5$

4 is not equal to -5, so -2 is not the solution for this equation.
