Identify like terms: Identify and combine like terms on the left side of the equation. 4x and 3x are like terms because they both have the variable x. Combine them by adding their coefficients: 4 + 3 = 7. So, 4x + 3x becomes 7x.Write simplified equation: Write the simplified equation. The equation now is 7x = 28.Divide both sides: Divide both sides of the equation by 7 to solve for x. Dividing both sides by 7 gives x = 28 / 7.Calculate x value: Calculate the value of x. 28 divided by 7 equals 4. So, x = 4.

4 x+3 x=28

Identify like terms: Identify and combine like terms on the left side of the equation. $\newline$ $4x$ and $3x$ are like terms because they both have the variable $x$ . $\newline$ Combine them by adding their coefficients: $4 + 3 = 7$ . $\newline$ So, $4x + 3x$ becomes $7x$ .
Write simplified equation: Write the simplified equation. $\newline$ The equation now is $7x = 28$ .
Divide both sides: Divide both sides of the equation by $7$ to solve for $x$ . $\newline$ Dividing both sides by $7$ gives $x = \frac{28}{7}$ .
Calculate x value: Calculate the value of x. $\newline$ $\frac{28}{7} = 4$ . $\newline$ So, $x = 4$ .
