Solve for x. -8x+21=53 Answer: x=

Isolate variable x: First, we want to isolate the variable x on one side of the equation. To do this, we will subtract 21 from both sides of the equation to move the constant term to the right side. -8x + 21 - 21 = 53 - 21Simplify equation: Now, we simplify both sides of the equation by performing the subtraction. -8x = 53 - 21 -8x = 32Solve for x: Next, we need to solve for x by dividing both sides of the equation by -8, which is the coefficient of x. -8x / -8 = 32 / -8Find value of x: After dividing, we find the value of x. x = -4

\newline

-8 x+21=53

\newline

Answer:

x=

Isolate variable x: First, we want to isolate the variable x on one side of the equation. To do this, we will subtract $21$ from both sides of the equation to move the constant term to the right side. $\newline$ $-8x + 21 - 21 = 53 - 21$
Simplify equation: Now, we simplify both sides of the equation by performing the subtraction. $\newline$ $-8x = 53 - 21$ $\newline$ $-8x = 32$
Solve for x: Next, we need to solve for $x$ by dividing both sides of the equation by $-8$ , which is the coefficient of $x$ . $\frac{-8x}{-8} = \frac{32}{-8}$
Find value of x: After dividing, we find the value of $x$ . $x = -4$
