Step-by-step explanation:

1(a) -4 + 7....is the same as... 7 - 4 = 3

(b) -2 - 9 = -11....for an easier trick...you just say..( 2 + 9 )= 11..then after obtaining your answer..put the negative sign(-) on your answer..(its only applicable if the numbers in the sum are all negative)

= -18

<h2>Answer: r = 7.</h2><h2>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~</h2>

$17 = r + 10$

Swap sides so that all variable terms are on the left hand side.

$r + 10 = 17$

Subtract 10 from both sides.

$r = 17 - 10$

<h2>Subtract 10 from 17 to get, you guessed it, 7!</h2>
