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

x ≈ - 1.83

Step-by-step 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
