The language is R5RS can I have the solution in steps thank you.

(let (11 (+ 2 1)) (e (/ 16* 4 4))) (t (length '(5 7)))) (if ( le) t 0)). ((lambda (x y) (+ 3 x (* 2 y))) (+ 3 3) (* 2 2)) (let ((a (lambda (b c) (+ b c))) (b 10) (c 5)) (+ (a 3 2) b c)) (define (x y z) ((lambda (y z) (- y z)) z y)) (x 35) (define (foo y) ((lambda (x) y) ((lambda (y) (* y y)) y))) (foo 3) (let (11 (+ 2 1)) (e (/ 16* 4 4))) (t (length '(5 7)))) (if ( le) t 0)). ((lambda (x y) (+ 3 x (* 2 y))) (+ 3 3) (* 2 2)) (let ((a (lambda (b c) (+ b c))) (b 10) (c 5)) (+ (a 3 2) b c)) (define (x y z) ((lambda (y z) (- y z)) z y)) (x 35) (define (foo y) ((lambda (x) y) ((lambda (y) (* y y)) y))) (foo 3)
