Question

Use a calculator to solve the equation.

−9.5x + 0.81 = −2.99

The solution is x =

Answer 1

x=0.4

Explanation:

Given function:

• -9.5x+0.81=-2.99
• find x

Combine first value by 0.81:

• -9.5+0.81=-2.99

• -19x/2+0.81=-2.99

Subtract 0.81 both from sides:

• -19x/2+0.81-0.81=-2.99-0.81

Simplifly -19x/2:

• -19x/2=-3.8

Multiply all terms by similar term:

• 2·19x/2=2·3.8

Divide both terms by -7.6:

• -19x/-19
• -7.6/19=0.4

Therefore, x=0.4.
