Answer:

x = 9

Step-by-step explanation:

Using the rule of exponents

$a^{m}$ × $a^{n}$ ⇔ $a^{(m+n)}$

Given

$11^{x}$ = $11^{4}$ × $11^{5}$ = $11^{(4+5)}$ = $11^{9}$

Since the bases on both sides are common, then equate the exponents

x = 9

Which is the best first step and explanation for solving this system of equations?

Volgvan

Answer:

x=-4/9, y=10/3. (-4/9, 10/3).

Step-by-step explanation:

3x+4y=12

3x=2y-8

--------------

2y-8+4y=12

6y-8=12

6y=12+8

6y=20

y=20/6

simplify,

y=10/3

3x=2(10/3)-8

3x=20/3-8

3x=20/3-24/3

3x=-4/3

x=(-4/3)/3

x=(-4/3)(1/3)=-4/9

x=-4/9, y=10/3. (-4/9, 10/3).
