Q. Kingsten (STN: E5821502658215026)\newlineDr−3-3eCE −4-4\newlineEnter the value of r r so that the expression 7(q+5) 7(q+5) is equivalent to (q+r)7 (q+r) 7 .
  1. Compare Expressions: Now, we compare the two expressions.\newlineWe see that 7q7q is common in both, so we just need to find the value of rr that makes 7r7r equal to 3535.
  2. Find Value of r: To find rr, we divide 3535 by 77.\newline35÷7=535 \div 7 = 5\newlineSo, rr should be 55.
