What is the solution to the equation 7 times open paren A minus 10 close paren is equal to 13 minus 2 times open paren 2 A plus 3 close paren ?

Distribute on both sides: 7A − 70 = 13 − 4A − 6, so 7A − 70 = 7 − 4A. Add 4A and 70 to both sides to get 11A = 77, then divide by 11: A = 7. The correct choice is C, A is equal to 7.
