Question

Solve for x. 1.1x + 1.2x - 5.4 = -10

Answer 1

x ≈ - 1.83

Explanation:

to solve for x in the question 1.1x + 1.2x - 5.4 = -10

we have

2.3x - 5.4 = -10

collect the like terms

2.3x = -10 + 5.4

2.3x = -4.2

divide both sides by the coefficient of x

2.3x/2.3 = -4.2/2.3

x = -1.826

x ≈ - 1.83
