DE = 5x-2

DF = 3(x+3)

3(x+3) = 3 + 5x-2

3x+9= 5x+1

2x=8

x=4

DE=5×4-2=18

Add the two expressions <br> 6q + 1 and q + 11
PSYCHO15rus [73]

Addition of 6q + 1 and q + 11 is 7q + 12

<em><u>Solution:</u></em>

Given that, we have to add the given two expressions

<em><u>Given expressions are:</u></em>

6q + 1 and q + 11

We have to add both the expressions

Addition of 6q + 1 and q + 11 = 6q + 1 + q + 11

Add the coefficients of same variable. Here "q" is present in two terms

Therefore, add 6q and q

Similarly, add the constants 1 and 11

<em><u>Thus finally addition is done as:</u></em>

6q + 1 + q + 11 = 7q +12

Thus addition of 6q + 1 and q + 11 is 7q + 12

Find x use picture for question. ​
katrin2010 [14]

Answer:

x = 8

Step-by-step explanation:

Firstly, create an equation or formula

- because they are congurent, IN = AT, so:

2x+10 = 26 (minus 10 from both sides)

2x = 16 (divide both sides by 2)

x = 8

Sub into the formula:

2 x 8 + 10 = 26

26 = 26
