# Solve the equation.

4.3x − 0.7(x+ 2.1) = 8.61

Question:

4.3x − 0.7(x+ 2.1) = 8.61

A
x = 2.8

Explaination

Original equation.

4.3x − 0.7(x+ 2.1) = 8.61

Apply the distributive property.

4.3x − 0.7x − 1.47 = 8.61

Combine like terms on the left side.

3.6x − 1.47 = 8.61

Add 1.47 to both sides.

3.6x = 10.08

Divide both sides by 3.6.

x = 2.8
