Answer :

To solve the equation [tex]\(7x - 15 = 20\)[/tex] given that [tex]\(x = 35\)[/tex], let's verify the solution step by step.

1. Substitute [tex]\(x\)[/tex] with 35 in the equation:
[tex]\[ 7(35) - 15 \][/tex]

2. Multiply 7 by 35:
[tex]\[ 7 \times 35 = 245 \][/tex]

3. Subtract 15 from 245:
[tex]\[ 245 - 15 = 230 \][/tex]

Thus, when [tex]\(x = 35\)[/tex], the left-hand side of the equation [tex]\(7x - 15\)[/tex] simplifies to 230. This confirms that the given solution satisfies the equation. Therefore, the result of the expression [tex]\(7x - 15\)[/tex] when [tex]\(x = 35\)[/tex] is 230.
