Solve 64^x = 16^x−1.
erica [24]
64^x=16^x-1====> Make the bases the same
4^3(x)=4^2(x-1)=> Solve for x by bringing down the exponent without the base.
3(x)=2(x-1)=====> Distribute
3x=2x-2======> Now solve for x
3x = 2x-2
-2x  -2x
x=-2
Therefore x is negative two

3(1.5x+9)= tell me NOW
Misha Larkins [42]

Answer:

x = -6

Step-by-step explanation:

Simplifying

3(1.5x + 9) = 0

Reorder the terms:

3(9 + 1.5x) = 0

(9 * 3 + 1.5x * 3) = 0

(27 + 4.5x) = 0

Solving

27 + 4.5x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-27' to each side of the equation.

27 + -27 + 4.5x = 0 + -27

Combine like terms: 27 + -27 = 0

0 + 4.5x = 0 + -27

4.5x = 0 + -27

Combine like terms: 0 + -27 = -27

4.5x = -27

Divide each side by '4.5'.

x = -6

Simplifying

x = -6

2x - 3y = -5<br> 5x - 22 = -4y<br><br> Solve In Multiplication Method
Nimfa-mama [501]

Answer:

(2, 3 )

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 5 → (1)

5x + 4y = 22 → (2) [ rearranged equation ]

Multiplying (1) by 4 and (2) by 3 and adding will eliminate the term in y

8x - 12y = - 20 → (3)

15x + 12y = 66 → (4)

Add (3) and (4) term by term to eliminate y, that is

23x = 46 ( divide both sides by 23 )

x = 2

Substitute x = 2 in either of the 2 equations and evaluate for y

Substituting into (2)

5)2) + 4y = 22

10 + 4y = 22 ( subtract 10 from both sides )

4y = 12 ( divide both sides by 4 )

y = 3

Solution is (2, 3 )
