First write down your equation. 3(x+2)=27. distribute the 3. 3x+6=27. move the 6 to the other side of the equal with the opposite sign. 3x=27-6. combine like constants. 3x=21. divide by three to get your answer for x. 3x/3=21/3. your answer is x=7

This is my question

Talja [164]

Answer/Step-by-step explanation:

∆ABC is similar to ∆CDE. Therefore, the ratio of their corresponding sides are proportional.

This,

$\frac{DE}{AB} = \frac{DC}{AC}$

$\frac{4}{3} = \frac{x + 3}{x + 1}$

Solve for x

$4(x + 1) = 3(x + 3)$

$4x + 4 = 3x + 9$

$4x + 4 - 4 = 3x + 9 - 4$

$4x = 3x + 5$

$4x - 3x = 3x + 5 - 3x$

$x = 5$

Use the value of x to find AC and DC

$AC = x + 1 = 5 + 1 = 6$

$DC = x + 3 = 5 + 3 = 8$

Which steps could be used to solve this equation?

Nesterboy [21]

Answer:

answer is option B

Step-by-step explanation:

ok the equation is 2/3 x +9 = 15

if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.

2/3x = 6

now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)

we multiply both side by reciprocal ie,

2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.

x = 6 x 3/2 = 18/2 = 9.

2x + y = 5<br> 4x + 2y = 10

Artyom0805 [142]

Answer: x= 5-y/2

y= 5-2x

Step-by-step explanation:

2x + y= 5

4x + 2y=10

Addition of the two equations gives:

6x + 3y = 15

6x= 15- 3y

x= 15-3y/6 or simplified to x = 5-y/2

3y= 15- 6x

y= 15-6×/3 or simplified to y= 5-2x
