<h2>Greetings!</h2>

When adding like terms, they simply add together:

6y + 3y = 9y

The rule of adding two powers are as follows:

x^{a} + x^{b} = x^{a+b}

So:

y^{4}  + y^{4} = y^{4 + 4} = y^{8}

So 6y⁴ + 3y⁴ = 9y⁸

72= 27+ 9s solve the equation
AVprozaik [17]

Answer:

s=5

Step-by-step explanation:

72=27+9s

Subtract 27 from both sides.

72-27=9s+27-27

45=9s

Divide 9 from both sides.

5=s

Solve the system by substitution.<br> x – 4y = -8<br> 5у – 1 = x<br> Submit Answer
Vikki [24]

Answer:

y = -7 and x = -36

Step-by-step explanation:

x - 4y = -8

5y - 1 = x

→ Substitute 5y - 1 into x - 4y = -8

5y - 1 - 4y = -8

→ Simplify

y - 1 = -8

→ Add 1 to both sides

y = -7

→ Substitute y = -7 into 5y - 1

( 5 × -7 ) - 1 = -36
