Question

Look at the equation 4x - 8.4 = 2x + 5. The terms 4x and 2x are like terms

because they are both written as a coefficient times x. To combine 4x and 2x,

you can subtract 2x from both sides of the equation. Write the equation in the

form ax + b = c. What is the solution of this equation?

Answer 1

In form ax + b = c: 2x - 8.4 = 5

Solution to equation: x = 6.7

Explanation:

4x - 8.4 = 2x + 5

2x - 8.4 = 5

2x = 13.4

x = 6.7
