x = number of domestic stamps

y = number of foreign stamps

Malik collects rare stamps and has a total of 212 stamps.

=> x + y = 212

he has 34 more domestic stamps than foreign stamps.

=> x = y + 34

which equation represents the total number of stamps malik collected?

x + y = 212

which equation represents the difference in the number of foreign and domestic stamps malik collected?

x - y = 34

which system of linear equations represents the situation?

x + y = 212
x - y = 34

10 − 7j + 7 = -10 − 4j What is j

Elena L [17]

Add the numbers 7 + 10
17 - 7j = -10 - 4j
subtract 17 from both sides
-7j = -27 - 4j
add 4j to both sides
-3j = -27
divide both sides by -3
j = 9

Solve for x. −5(x−4)=−30 Enter your answer in the box.

saveliy_v [14]

First divide both sides by - 5,

$x - 4 = 6$

Move the constant to the right side of the equation and change its sign (-4 => +4)

$x = 6 + 4$

Add the numbers,

$x = 10$
