The equation is 1.4 + t = 3.6 .

Apply subtraction property of equality: Subtract 1.4 from each side.

t + 1.41.4 = 3.6 1.4

t + 0 = 3.61.4                 (Apply additive inverse property: 1.41.4 = 0)

t = 3.61.4                       (Apply additive identity property: x + 0 = x)

t = 2.2                                (Subtract: 3.6 1.4= 2.2)

Check:

To check the solution, substitute t= 3.2 in original equation.

1.4 + t = 3.6 1.4+2.2 = 3.6

3.6 =3.6                              (Add:1.4+2.2 = 3.6)

The statement is true.

Graph the solution on number line.

\
• First draw a number line.
\
• Mark a dot at 2.2 on  the number line.
