Answer: x=0

Step-by-step explanation:

Given

3(x+14)=42

Distributive property

3x+42=42

Subtract 42 from both sides

3x=0

Divide 3 on both sides

x=0

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

Given

3(x+14)=42

Divide 3 on both sides

x+14=14

Subtract 14 on both sides

x=0

Both ways are fine

Hope this helps!! :)

Answer:

Step-by-step explanation:

So we have the equation:

$3(x+14)=42$

Divide both sides by 3:

$x+14=14$

Subtract 14:

$x=0$

The value of x is 0

Which number should each side of the equation 3/4 = 9 be multiplied by to produce the equivalent equation of x = 12?

Tema [17]

You need to multiply both sides of the equation by the reciprocal of 3/4. The reciprocal is 4/3 and 4/3 multiplied by 9 = 12. So x = 12 because a number times the reciprocal is one.

I can’t see the photo so I can’t tell you the answer but good luck. Congruent means they look the same I think.

Solve for x: −2(x 3) = −2(x 1) − 4. 2 3 all real numbers no solution

Crank

-2(x + 3) = -2(x + 1)
-2x - 6 = -2x - 2
-2x + 2x = -2 + 6
0 = 4

Therefore, the system has no solution.

Four to the power of three times four to the power of negative six is equal to four to the power of five times four to the power

ivann1987 [24]

The blank is -8

Step-by-step explanation:

Let us revise some rules of indices:

$a^{m}$ × $a^{n}$ = $a^{m+n}$
$a^{m}$ ÷ $a^{n}$ = $a^{m-n}$
$a^{m}$ = $a^{n}$ , them m = n

∵ $4^{3}$ × $4^{-6}$ = $4^{5}$ × $4^{x}$

∵ All bases are equal

∴ Use the first and third rule above to find x

∵ $4^{3}$ × $4^{-6}$ = $4^{3+-6}$

∴ $4^{3}$ × $4^{-6}$ = $4^{-3}$ ⇒ L.H.S

∵ $4^{5}$ × $4^{x}$ = $4^{5+x}$ ⇒ R.H.S

Equate L.H.S and R.H.S

∴ $4^{-3}$ = $4^{5+x}$

Equate the indices of the two sides

∴ -3 = 5 + x

- Subtract 5 from both sides

∴ -8 = x

∵ x represents the blank

∴ The blank = -8

The blank is -8
