Answer: x = 7, y = -3
<u>Step-by-step explanation:</u>
3y = 26 - 5x --> added 5x to both sides to get: 5x + 3y = 26
Elimination method (I am going to eliminate "x":
5x + 3y = 26 → 6(5x + 3y = 26) → 30x + 18y = 156
6x + 7y = 21 → -5(6x + 7y = 21) → <u> -30x - 35y</u> =<u> -105</u>
-17y = 51
<u> ÷-17 </u> <u>÷-17</u>
y = -3
Now, input y = -3 into one of the original equations to solve for "x":
3y = 26 - 5x
3(-3) = 26 - 5x
-9 = 26 - 5x
-9 -26 = -5x
-35 = -5x
7 = x

Answer:
18x^5y
Step-by-step explanation:
Divide 36 by 2 first : 18
since you are dividing, you subtract the exponents:
x^8 - x^3= x^5
y^4-y^3= y^1 but you usually just write y
