Answer: a = 29

Step-by-step explanation:

5a - 100 = 45

To find the value of a, put a the subject of the equation

5a = 45 + 100

5a= 145

Divide both sides by 5

a = 145/5

a = 29

Check:

5 (29) - 100= 45

145 - 100 = 45

I hope this is clear, please mark as brainliest answer.

miv72 [106K]

Answer:

x=12, y=6

Step-by-step explanation:

Very simple!

Just substitute 0 for y and solve for x!

$x+2(0)=12$ (anything times 0 equals 0!)

$x=12$

Now you can do the same thing but substitute 0 for x!

$0+2y=12$

$y=6$
