# How do you solve 15t - 5= - 35?

Feb 2, 2017

t = -2

#### Explanation:

Rearrange to get the terms in t on one side, and the numbers on the other. Make sure you apply the rule of "change the side = change the sign".

$15 t - 5 = - 35$

$15 t = - 35 + 5$

$15 t = - 30$

$t = - \frac{30}{15} = - 2$

$t = - 2$

#### Explanation:

$15 t - 5 + 5 = - 35 + 5$

but -5+5=0 giving

$15 t + 0 = - 30$

$15 t = - 30$

Divide both sides by 15

$\frac{15}{15} t = - \frac{30}{15}$

but $\frac{15}{15} = 1 \text{ and } - \frac{30}{15} = - 2$

$1 \times t = - 2$

Not that is not good mathematical practice to show the $1 \times t$ it should just be $t$

$t = - 2$
