Question

2.Solve the equation. Round the result to the nearest hundredth.
14.1 - 0.3x = 1.3x - 4.2

3.Multiply the equation by a power of 10 to write an equivalent
equation with integer coefficients.
6.2x + 4.5 = 3.8x + 7.9

4. Rewrite the equation so that y is a function of x:when x = -1

Answer 1

2.

14.1 - 0.3 x = 1.3 x - 4.2

Add 0.3 x to both sides

14.1 = 1.6 x - 4.2

Add 4.2 to both sides

18.3 = 1.6 x

1.6 x = 18.3

x = 18.3 / 1 .6 = 10 ∙ 18.3 / 10 ∙ 1 .6 = 183 / 16 = 11.4375

x = 11.44

to the nearest hundredth

3.

6.2 x + 4.5 = 3.8 x + 7.9

Multiply both sides by 10

62 x + 45 = 38 x + 79
