Question

8.9 – 1.4x + (–6.5x) + 3.4 simplify this expression

Answer 1

12.3 - 7.9x

Explanation:

I added the numbers without variables first then I added the numbers with variables:

8.9+3.4 = 12.3

-1.4x + -6.5x = -7.9x

Answer 2

x = 1.6

Explanation:

Simplify the expression

8.9 – 1.4x + (–6.5x) + 3.4

8.9 - 1.4x + (-6.5x) + 3.4

collect like terms

8.9 + 3.4 - 1.4x - 6.5x

12.3 - 7.9 x = 0

take 7.9x to the left side

12.3 = 7.9x

divide both sides by 7.9

x = 12.3/7.9

x = 1.55696202532

x = 1.6
