<h2><u>Required Answer</u>:</h2>

Given pair of expression :

\longrightarrow \sf {(4x -7) \: and \: (7-4x) }

<u>Solution</u> :

Firstly put the sign of addition (+) at the place of and.

\longrightarrow \sf {(4x -7) + (7-4x) }

Now, remove the brackets.

\longrightarrow \sf {4x -7 + 7-4x }

Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.

\longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}}

\implies \sf \red {0 }

<u>So, the answer is 0.</u>

The given regression shows the relationship between the numbers of car washed(x) and the amount earned for charity(y).

y = 10x + 20

We are to calculate the amount of charity if 50 cars are washed. Number of cars are represented by x, so by substituting x = 50 in above equation we can find the amount of charity that is earned by washing 50 cars.

y = 10(50) + 20 = $ 520

Thus, the charity can earn $520 if 50 cars come in for a wash.
